FENERBAHCE coach Vitor Pereira is tipped for the sack if they lose to Celtic in their Europa League tie.

The Turkish cracks, who are due in Glasgow tomorrow night, are in meltdown after losing 3-2 to bitter rivals Besiktas on Sunday.

And that sparked a frosty bust-up with star striker Robin van Persie, who was caught on camera almost snubbing his manager's handshake during the match.

But Parkhead coach John Kennedy last night warned against complacency ahead of the match after watching the Dutchman come off the bench to score in the tinderbox tie.

And he warned Celtic to be wary of a Van Persie backlash at Parkhead.

Kennedy said: “We don’t take any positives from talk of Van Persie having problems with the coach.

"Based on what I’ve seen, Van Persie had a big impact on the game when he came on. I’d be very surprised if he didn’t start against us on Thursday. He is their best striker.

“Van Persie is 32 now and obviously at the other end of his career. But he is still a top, top player.

“His finish on Sunday night was excellent. He is very calm in front of goal. There is intelligence there. He’s still got legs and he’s definitely got a football brain. That’s sometimes the most important thing.

“With the experience he has, he looks after his own game. He is still a threat. He is always there or thereabouts when chances come into the box.

“He is scoring goals and they have got that in different areas of the pitch. We know what his strengths are and we need to make sure we look after that.”

Fenerbahce are on the same number of points as top of the table Besiktas in the Turkish Super League, but the home to defeat to Molde in the opening Europa League fixture and his handling of Van Persie, reportedly on a weekly wage of £220,000, has put huge pressure on Pereira, who was at one stage in the running for the Rangers job.

Especially since a win for Celtic would all-but make Group A something of a three-way fight between the Scottish champions, Molde and Ajax who face one another in Norway on the same night.

Fenerbahce spent a lot of money in the last transfer window, but the great leap forward has not happened. Celtic will be favourites, but Kennedy urged caution.

He said: “Listen, people are saying Fenerbahce are a club which is struggling, but they’re not.

"They lost on Sunday night and had a disappointing result in the Champions League against Shakhtar Donetsk.

“But outwith that, they have been quite convincing from what I have seen. They have a lot of top players. They are in transition, with a new coach this season and around eight new players. But the players they have are very impressive - Van Persie, Nani and several other top-class players.

“It will be a tough game. Molde obviously got a good result against them two weeks ago but we have to make sure we bring our ‘A’ game on Thursday if we are to get anything out of the match.

“We just need to make sure we concentrate on ourselves. We need to make sure that when we get forward we create chances and that we are more clinical than we were on Saturday.

“There are areas of Fenerbahce’s game we will look at. We look at every team we play in depth, domestic and European. It was nice to see them live and see the whole picture. We will look to pinpoint any weaknesses they have and do our best to use them to our advantage.”
