olton boss Owen Coyle has brushed off Manchester United manager Sir Alex Ferguson's claim that Tuesday's game will be "easy" for Chelsea.[LNB] United dropped points in the Premier League title race after a goalless draw at Blackburn on Sunday.[LNB]In his post-match comments, Ferguson accepted it would be difficult for his side to catch Chelsea, who are now a point ahead with a match in hand.[LNB]"We have a lifeline if Chelsea blow it. But in my eyes they have an easy game against Bolton on Tuesday," said the United boss.[LNB]Coyle has more important issues of his own with Bolton five points above the relegation zone having lost their last three matches.[LNB]So he was not concerned by Ferguson's attempt at playing psychological games with his players ahead of their trip to Stamford Bridge.[LNB]"That's up to him. That's his opinion, he has it and he's given it - all very well," said Coyle.[LNB]"I'll concentrate on what we can do and not what anyone else says."[LNB]Although no-one realistically gives Bolton a chance of causing an upset at Stamford Bridge, Wanderers captain Kevin Davies believes he has spotted a chink in their armour.[LNB]Davies thinks the relationship between strikers Didier Drogba and Nicolas Anelka is not what it should be and the Frenchman has a familiar unhappy look on his face.[LNB]"It is always difficult to say with Nicolas, he's such a hard person to read," said Davies, who played alongside Anelka during his spell at the Reebok Stadium before his move to Chelsea.[LNB]"You never quite know what's going through his mind.[LNB]"There seems to be something not quite right with him and Didier Drogba. I'm not sure they get on very well."[LNB]Davies told the Bolton News: "There doesn't seem to be a great bond when they play together, whereas Nicolas lights up when he plays on his own.[LNB]"You can't deny he's a great player capable of making something out of anything - but at the moment, you feel he's just not that happy."
