If you have any questions for Sean about Borussia Dortmund v Manchester City or the other games in the Champions League this week, drop them into the comments section below.

11am: Sean Ingle is in the comments section answering questions.

PsychoGeorge begins with a question about Shakhtar Donetsk v Juventus: "The game is odds on with the bookmakers for the draw. Is a stitch up about to take place?"

Sean replies:

I don't think we're about to be witness a repeat of Austria v Germany from Italia 82 but at the same time, I can understand why the draw is odds on with the bookies. If the game is a draw with 20 minutes to go, why wouldn't the players initiate a gentlemen's agreement? But initially Juventus might go for the win, which would lead to them avoiding Barcelona, Dortmund, Bayern, Manchester United and possibly PSG in the last 16.

11.06am: JustDontDoIt asks: "Could you speak with a few Dortmund fans (or German football fans in general) and let us know their opinions on the Premier League and English teams? Do German football fans have more of an interest than most English fans would have in the Bundesliga?"

Sean replies:

I don't think it would be right to overly generalise but, from a small sample size, the Germans I speak to keep abreast of the Premier League, and generally enjoy it, but they prefer the Bundesliga. Why? Mostly because it's their home league, of course, but also because of the cheaper prices, terracing, closer connections with fans etc. I would say more German fans keep an eye on the English football than vice versa. If the English equivalent of Poldolksi and Mertesacker went to, say, Leverkusen that would change of course.

11.08am: MightyBlues asks: "Aren't Chelsea being written off prematurely? Shakhtar aren't going to want to finish second this year with the daunting possible fixtures they could face in the knock-out stages and they are incredibly good in their very intimidating stadium. If Chelsea were in Juve's position, I wouldn't be very confident at all."

Sean replies:

Quite possibly. The bookies odds imply there's about a 55% chance of a draw between Shakhtar and Juventus, so it's not a given that Chelsea are out. Yet.

11.13am: DanteMeetsBosch asks: "Given the choice, do you think City want to be in the Europa League, or will they secretly be happy with finishing bottom? Is tonight more about restoring pride than qualifying for another competition?"

Sean replies:

Mancini was asked this at the press conference yesterday and he was quite insistent:

"It will be difficult because in the Europa League you play Thursdays so you don't have a lot of rest before Premier League matches. But we must try to play in the Europa League. We need to stay in Europe."

Is the Europa League a hindrance? Not if you go out early in the knockout stages, as City showed last year. But there are a number of Russian and Ukrainian teams in the competition – and it would affect City's chances if they were playing, say, Metalist or Rubin Kazan on Thursday away and had a big game on the Sunday.

11.20am: Jezz85 wants some predictions: "How far can Dortmund go in this season's Champions League? Which teams will they want to avoid in the round of 16?"

Sean replies:

I backed them at 25-1 in the summer (they were actually more like 40s after the draw) so I hope Dortmund go all the way. They could still face Juventus, Milan and Arsenal in the last 16 so nothing is a given, but I'm hopping they will go deep into the competition.

11.21am: DelGriffith asks: "Is Wenger doing the right thing in leaving his big hitters at home? Finishing top will not guarantee a good draw as the likes of Dortmund, Real Madrid and Juventus could finish second, but at least winning the group would mean avoiding Barcelona."

Sean replies:

I can see where you are coming from, but you'd expect Schalke to beat Montpellier and Wenger reckons his big names are knackered, so you can understand his logic.

11.23am: Jacktatum asks: "Was Wenger just having a bad day yesterday or is the criticism really getting to him this season? If Arsenal finish, say, sixth in the Premier League, will he be pushed or step down, or is he determined enough to stay?"

Sean replies:

The criticism from some fans – and the repeated questions about it from journalists – are getting to Wenger. Wouldn't you be frustrated if people kept questioning you at work? I thought he made a decent point in his press conference last week before the Everton game, when he said:

"Last season we finished third. Honestly, I don't think there was much more in that team than third. Like when we won the Premier League with zero defeats, which no one else has done, you think there is not much room to do much better. At the end of the season I want to stand in front of my mirror and think: 'Have I done all I can?' That's all."

This Arsenal side isn't on the same pitch as the Invincibles. It isn't even near the title-winning team of 1998, which was rickety in places (Christopher Wreh anyone?). If Arsenal finish fourth, Wenger will regard that as pretty much the best he could have achieved, given his current squad... and he will stay on. If they finish 10th, say, then we are in unchartered territory.

11.27am: citizenthirdmankane asks: "Are you enjoying Dortmund?"

Sean replies:

I only had a look around the Christmas markets yesterday so it would be unfair of me to compare it with, say, Hamburg, Berlin or Munich yet. But I am huge fan of Germany. It's a great country.

11.29am: Damien asks: "Do you see Klopp coming to England some day or will he stay with Dortmund long-term?"

Sean replies:

Not sure. It would be interesting to see what would happen if a certain Russian oligarch came in during the summer and offered him megabucks. That said, Klopp seems happy in Dortmund and he has a young and brilliant team that – providing they don't sell too many players – could be one of Europe's elite for the next decade.

11.30am: mackben asks: "How terrible are the proposals to double the size of the Champions League? It's all very scratchy at the moment but considering the current quality on show, how can increasing teams be a good thing?"

Sean replies:

It's an awful idea. I imagine the 64-team format would lead to 16 groups of four, with groups A-H and I-P played in alternate weeks. So you would get pretty much wall-to-wall Champions League coverage every midweek from September to early December. A 64-team unseeded knockout might be interesting...

11.32am: noscorebore asks: "Is Celtic qualifying for the knockout stages a sign of Scotland going forward or Europe going backwards?

Sean replies:

It's hard to make sweeping judgements based on six group games in isolation. There's just not enough data to do that. If Celtic build on their brilliant performance this year, and they are joined by other Scottish teams doing well in Europe, it'll be the former. But too early to say.

11.37am: NyeBaron asks: "Did Chelsea winning the tournament cover up for the fact the Premier League is not what it once was?"

Sean replies:

Possibly, but again it's difficult to make sweeping judgments yet. Don't forget in the 2005-06 season, Arsenal were the only English side that made the quarter-finals, yet the following year three Premier League teams made the semi-finals.

Sometimes countries have bad years in the Champions League. That said, the current Manchester City, Manchester United and Chelsea sides all have fairly obvious problems that the likes of the Sir Alex Ferguson's best teams, Arsenal's Invincibles (and before) and Chelsea under José Mourinho didn't have.

11.41am: iexclaim asks: "Do you think the Champions League needs an overhaul? It seems to have lost quite a bit of its magic in recent years. Are you in favour of expanding the number of teams?"

Sean replies:

It might need an overhaul, but not of the type that Uefa are proposing. Call me old-fashioned, but I liked the old European Cup, Cup Winners' Cup and Uefa Cup formats. I accept they will never come back.

11.48am: dublinroo takes issue with the usual complaint about the Europa League schedule: "Playing in the Champions League on a Wednesday and then the Premier League on Saturday is normal; but it's claimed that playing in the Europa League on Thursday and the Premier League on a Sunday is a disaster. I fail to see the huge difference."

Sean replies:

I'm not sure it's completely an excuse. There are two extra games in the Europa League and there are more possible long-haul flights. Look at the current standings. There are trips to Bucharest, Istanbul, Dnipropetrovsk, Kazan, Moscow, Kharkiv in the offering as well as to third-place teams in the Champions League – Cluj, Athens, Rosenberg, Bate in Belarus, Kiev, Zenit St Petersburg etc.

11.51am: MrKiddon asks: "Spain and Germany will have three teams in the knockout stages of the competition, but England will only have two in the last 16. Do you think this points towards a decline in the Premier League?"

Sean replies:

It's too early to say. Both Chelsea and Manchester City were drawn in very tough groups – Real Madrid, Shahktar, Juventus and Dortmund are contenders to go all the way. I don't think you could say that any group had three teams that strong in it.

11.53am: RonanS asks: "How successful do you think Paris Saint-Germain could be in the later stages?"

Sean replies:

I've seen PSG a few times this season and haven't been particularly impressed. But remember Madrid in 99-00, and even Chelsea last year? Few gave them a chance in December, yet come May they were lifting the trophy. Shock results do happen and PSG have the players to do a certain amount of damage. I would be surprised if they got as far as the semi-finals; they just don't seem a cohesive enough team at the moment.

12.01pm: Thanks for all your questions and comments everyone. Sean has signed off. Hopefully he will make it back to the Christmas markets to see the city's most gloriously adorned Christmas tree.

Elsewhere on the football site we have Rafa Benitez in the Gallery and a preview of Arsenal's game tonight. Thanks.
