Celtic will seek "clarification" from UEFA over referee Alberto Undiano Mallenco's performance in the 3-0 Champions League defeat by Juventus at Parkhead on Tuesday night, manager Neil Lennon has revealed.
The Spanish official came in for widespread criticism of the way he allowed the Serie A side to manhandle Celtic players at times in the penalty area during the first leg of their last 16 tie.
Lennon was seething after the game and ahead of tomorrow's Clydesdale Bank Premier League game against Dundee United at Parkhead he confirmed that the Scottish champions would be looking for an explanation from European football's governing body.
He said: "The referee didn't do his job and there has been a lot of talk since Tuesday night regarding it, so we are looking for clarification on the referee's decisions during the game.
"We are going to compile a DVD and send it to them (UEFA) and wait and see what answers we do get.
"It's a myth that Juventus 'did their homework'. That's rubbish. Juventus defend like that week-in, week-out in Serie A.
"If anything we had done our homework and we made sure the referee was aware of it and he was looking at it time and again and Juventus went unpunished.
"We needed a strong referee and we didn't have that.
"It was blatant. I have seen photographs where the shirt was almost pulled off Gary Hooper's back and he ends up in the goal at one stage.
"I admire Gary for keeping his cool, if it had been me I might have got sent off for something I would have regretted later on.
"Gianluca Vialli (former Juventus skipper) said we should have had two penalties, Graham Poll and Dermot Gallagher (former referees).....Trevor Francis said that even in his time playing in the 80s (in Italy) it was never as blatant as what he seen the other night, so these guys can't all be wrong and the referee right."
The fall-out from the Juventus defeat, which almost certainly renders the return game in Turin redundant, dominated Lennon's press conference at the club's Lennoxtown training complex.
The former Celtic skipper stood by his decision to play Efe Ambrose, who only returned to Glasgow early on Tuesday morning following Nigeria's African Nations Cup final win over Burkina Faso on Sunday night.
Lennon revealed the defender had apologised to him for his ropey performance and also revealed that midfielder Kris Commons had been "dealt with internally" for being critical of Ambrose and the rest of the Hoops defence.
"On reflection, if I had the opportunity to change anything I wouldn't, I would go with the same team," said the Northern Irishman.
"Efe made two basic mistakes but he had the clear-cut chance of the game for us and if he had scored then no one would have been talking about his selection.
"I spoke to him and he said he was ready to play.
"When you make basic mistakes like Efe did then you are open to criticism and he has apologised for his performance.
"However, he has been a fantastic signing. He has added a new dimension to the way we play and some of his performances in the Champions League this season has been of an exceptionally high standard and so he doesn't need to apologise, we all have bad nights."
After the game Commons talked about "very sloppy individual mistakes" and the Scotland international specifically berated Ambrose, saying: "If he felt good then he should have put in a better performance."
"It was heat of the moment stuff," said the Parkhead boss.
"I have spoken to Kris about it and it has been dealt with internally, and there is no bad feeling from anyone.
"Kris really cares and he was disappointed but he did overstep the line a little bit. Sometimes you have to keep your emotions in check."
Lennon's Twitter account in the wake of the Juventus defeat displayed a robust exchange of views with followers, mostly about his selection of Ambrose but he played it down, saying: "Sometimes my missus takes over.
"She gets a little bit upset at some of the abuse at times.
"If people want to put it in the press, that's fine.
"I enjoy speaking to some of the fans when they ask questions.
Tomorrow afternoon, as Celtic return to domestic duties, Lennon will come up against one of his former Hoops team mates, Jackie McNamara, who recently took charge of the Taysiders.
He said: "I think he has taken over a good squad, Peter (Houston) left Dundee United pretty healthy.
"Probably league results didn't reflect that but Jackie has changed things around a little bit."
