1) Good old Zlatan

A cynic does not have to look hard to find much that's distasteful about the megabucks gloss of the Champions League and a player who is paid €55m-a-year is distasteful in the extreme. But, it's hard not to raise a guilty smile about someone as ludicrously enjoyable as Zlatan Ibrahimovic. His first-half hat-trick for PSG against Anderlecht was a one-man marketing campaign for the excess and excellence of the competition: the first was a simple enough tap-in, the second a back-heel rabona, and the third a 40-yard screamer into the top corner. As if to point out he wasn't done there, he scored a fourth with the outside of his boot. Ignore the finances involved, and it's simply a pleasure to watch someone play the sort of football the rest of us are only capable of in our dreams. Tom Bryant

2) Do you think Uefa will act sufficiently? Really?

Perhaps the saddest thing about the racist abuse that Yaya Touré was subjected to in Moscow on Wednesday night is that it no longer comes as a surprise. We have been here countless times before, which was a point that Touré made afterwards, when he urged Uefa to take the strongest possible action. Vincent Kompany took a similar line when he tweeted: "Racist chants again in Moscow today.. We've all said enough. @UEFAcom, @GovernmentRF, CSKA, all eyes are on you now.. #StopRacism." Sadly, and depressingly, European football's governing body is weak when it comes to dealing with racism. This is an organisation that believes a player carrying the name of a betting company on his pants is a more serious issue than a footballer being targeted because of the colour of his skin. Touré talked about CSKA being banned from using their stadium for a couple of years – the sort of punishment that would demonstrate Uefa is committed to removing this stain from our game. More likely is that CSKA will be fined a paltry amount. As for Russia, we await the response from CSKA and the national football federation with interest. Stuart James

3) Dortmund's marksmanship undid Arsenal

The official Uefa statistics said that Dortmund had three shots on target but it was difficult to remember the one that Wojciech Szczesny stopped. The Arsenal goalkeeper was a virtual bystander. So, essentially, this was a cold-eyed demonstration from Dortmund in how to convert the big chance when it comes. Jürgen Klopp's team pressed and they fractured Arsenal's rhythm but it was in front of goal where they taught their opponents the hardest lesson. There was not a person inside the Emirates who thought that Robert Lewandowski was going to miss his 82nd minute volley on the counterattack, least of all the Poland striker himself. David Hytner

4) Chiellini costs Juventus

Juventus imploded as a team against Fiorentina last weekend, so at least they can say there were improvements tonight, when only two of their players made a show of themselves against Real Madrid at the Bernabéu. Arturo Vidal could have picked up at least three yellow cards for persistent transgressions, but only got the one. Good news for fans of slapstick: were he sent off, the world would have never witnessed his hacking up a divot the size of a small planet while missing the ball itself, tripping over his standing leg, skittering across the turf on his buttocks with an astonished look on his face, then having the chutzpah to claim for a penalty. A treat on so many levels. Don't go changing, Arturo. Giorgio Chiellini's meltdown was more costly for the away team. In the first half he needlessly hauled Sergio Ramos to the ground by the neck, conceding the penalty that decided this match, then got himself sent off for fiddling with Cristiano Ronaldo's face, a flapping nonsense that probably only merited yellow, but was stupid enough to give the referee an opportunity to flash red. Chiellini will want to take a long look at himself, because Juve were definitely the better team when it was 11 versus 11, Claudio Marchisio, Carlos Tevez, Fernando Llorente and Paul Pogba buzzing around in the bothersome manner. If they can just put a stop to the daft mistakes and rushes of blood, they're an exciting enough side to go deep in this season's Champions League. As for Real? Well, they won't fancy the upcoming trip to Turin, a match Juve won't want to lose after their slow start to this group. But first things first: what if they play like they did during the final exchanges here – when Juve went down to ten and passes refused to stick – in Saturday's clásico? Good luck, chaps. Good luck.

5) Neymar still struggling to make an impact

Considering his price tag, the Brazilian forward has not had the kind of impact Barcelona would have hoped. Against Milan he had a very, very quiet game and only flickered twice during the whole match before being replaced by Pedro with 10 minutes remaining. And with Alexis Sánchez also not at his best, Barcelona were left to rely, as with so many times before, on Lionel Messi for the equaliser at the San Siro. The more worrying thing, perhaps, was that they did not create that many clear chances against a pretty average Milan side who were pushed back for the entire second half. Oh, and one more thing to add from the game: Kaká was brilliant. Marcus Christenson

6) It's too soon to hail Fernando Torres's latest return

That Fernando Torres is a confidence player seems very clear: picked for the match against Schalke over Samuel Eto'o –who most had expected to start – he shone with a bustling, powerful performance. José Mourinho has been acknowledged as a master man manager and playing Eto'o against Cardiff City in the Premier League while saving Torres for the Champions League clearly gave the Spaniard some extra strut. Torres is back, was the post-match story. However, we've seen this before. Last December he kicked off Chelsea's 8-0 rampage against Aston Villa with his seventh goal in six matches once again to prompt headlines hailing his return. His next Premier League goal came midway through May, while the only goals he scored in January and February came against Brentford and Middlesbrough in the League and FA Cups. It's probably worth witholding judgment as to his latest return for a while yet. TB

7) Costa a cut above

No wonder the Brazil coach Luiz Felipe Scolari is determined not to let Diego Costa slip through the net. The Brazil-born striker is considering registering for Spain despite having played in two Brazil friendlies and Scolari is thunderous about the situation: "I have the legal authority and freedom to call him up whenever I think I should do so and no-one else … and I'm thinking of giving him a call-up." Costa is currently the leading scorer in La Liga with 10 goals in nine appearances and he was brilliant again on Tuesday night as Atlético Madrid hammered Austria Vienna. His first was majestic: a run from the halfway line into the box, through two tackles, and a neat stroked into the corner. Atlético have reportedly put a £35m price tag on him. Expect someone to test their resolve in January. TB

8) Celtic's achievement overshadowed

If Celtic have got any sense, their Champions League training sessions will simply involve leaning against buildings. Because after their unlikely heroics last season, their impressive display against Barcelona this season, and their victory over Ajax on Tuesday night, it seems they are at their best with their backs to the wall. Having lost Victor Wanyama and Gary Hooper over the summer, and without their captain, Scott Brown, Adam Matthews and Kris Commons, they managed to fend off Ajax with a performance that may not have been pretty but was resolutely gritty. Ajax's manager Frank de Boer was less than impressed. "Celtic did not create anything but scored two goals," he sniffed, his fury clear. It is a shame for Celtic that he was not more gracious (though hardly unexpected) because his comments and the behaviour of Ajax's fans – who are being investigated after being accused of tearing up seats – grabbed headlines rather than the fact Celtic may yet qualify despite the difficulty of being in a group comprising Barcelona, Milan and Ajax.

9) Moyes still struggling to win hearts and minds

Manchester United's win over Real Sociedad will not have changed many people's minds about the club's direction under David Moyes. Those who are convinced the manager is on the wrong track will point to the periods were United lost control in midfield to erratic opponents and defended with panic, while those who think the future holds promise will highlight, in particular, the vibrance of the team's attacking, which was let down only by wonky finishing. Wayne Rooney sure enjoyed the freedom given to him by Robin van Persie's absence but cannot be said to have made the most of it. Paul Doyle

10) Come back Kompany

If Manchester City needed any reminders as to Vincent Kompany's worth to the side, it came against CSKA Moscow. The Russian side had failed to score in six of their seven previous matches before facing City. One look at a back four that had Javi García and Matija Nastasic at its heart, and their eyes lit up. Manchester City were a defensive shambles against CSKA Moscow and were frequently undone by simple, direct passes over the top. It didn't help that neither of the two deep-lying midfielders, Yaya Touré or Fernandinho, tracked back but Joleon Lescott must be wondering just why he is on the bench while someone as defensively inept as García is in the starting lineup.
