Uefa says it will not take disciplinary action against Neil Lennon despite the Celtic manager claiming the referee was "very pro-Juventus" during Tuesday night's Champions League match between the teams.

Lennon was angered at the failure of the Spanish referee Alberto Undiano Mallenco to award his team at least one penalty for grappling by Juventus defenders at Celtic corners.

After the match, which Juve won 3-0, the manager said of the referee: "I thought he was poor. I thought he was very pro‑Juventus. I was disappointed with his performance to say the least."

A Uefa spokesman confirmed on Wednesday afternoon that there has been no suggestion of sanctions being taken against Lennon for his comments after a review of the post‑match interviews.

Lennon said fouls on Celtic's players at corners were overlooked. "They were being manhandled. They were being fouled. It's not rugby we're playing. Are the rules different in Spain or in Italy? On that showing, they must be. It looked like the Juventus players were fouling at every opportunity."

The manager was not the only figure at Celtic to be unhappy with Juventus's tactics. Mikael Lustig, the Scottish champions' Swedish defender, said: "They used a lot of arms when they were defending set-pieces. We tried to speak to the referee but he wouldn't listen.

"If he looked closely at the Juventus players, he would see that they weren't looking at the ball. All they did was look at the players and wrap their arms around us. It's really tough to score like that."

Lustig echoed Lennon's sentiment that Celtic require a "miracle" to progress to the quarter-finals after the damaging first‑leg defeat. Nonetheless, Celtic rightly took confidence from their performance in long spells against the team sitting at the top of Serie A.

"We made a lot of chances but didn't take them," Lustig said. "We had over 10 corners and sometimes we were close but they defended well.

"Against a team like Juventus, if you get around 10 corners you need to score from them if you are going to win the game.

"Over the game, Juventus only created four of five chances and scored three goals. We've created 13 maybe and not scored. We now want to go and show we are a good football team. I think we showed that in parts already but after they scored the second, we didn't play that well.

"Between the first and second goals we were absolutely the better team. I think the score flattered them."

Although that may be true, Celtic must somehow maintain spirit for what appears a thankless task in Turin on 6 March. Juventus have lost only two home matches all season.

"If you say 'yes' then it's a waste of time going over there," insisted Lustig's fellow defender Kelvin Wilson when asked if the tie is already finished. You have to remember anything can happen in football. Look at Liverpool – they were 3-0 down in the [2005] final and came back to win it. That was against a great Milan team.

"It's going to be hard, we're not stupid. But we're not going to write it off."

Celtic have already upset the odds in this European campaign by defeating Barcelona in Glasgow. That result, in November, reverberated around Europe, as would an unlikely overturning of a 3-0 deficit against Juventus.

"I think the Barcelona win can inspire us, although we can't keep living off that one," Wilson added. "It is going to be tough, but we will have a go. It will without a doubt need one of the club's greatest ever performances to turn this around. Especially at their place. Juventus are top of Serie A and they haven't lost many games at home.

"But we'll go and have a go, that's all we can do. We are a confident bunch of boys."

Wilson was more sanguine about the antics of the Juventus players. "I think that's what Italian defenders are renowned for: making sure they get hold of you," he said. "I'm a defender myself so I'm not going to say bad things about it. It's good defending in my eyes. I'll do the same at the other end. But as a striker it will be a bit frustrating.

"That's football. You've just got to get on with it at times. You can't always moan about decisions."
