Chelsea are a 'wounded animal' warns Allardyce

Blackburn manager Sam Allardyce (pictured) has warned his players to expect Chelsea to react like "a wounded animal" after their Champions League mauling by Jose Mourinho's Inter Milan side.

Allardyce said Chelsea, who visit Ewood Park tomorrow, had receiving a "massive kick up the backside" from Inter but is hoping their players will suffer from fatigue. He said: "I'm not sure it's a good time to play them but the only thing we do know is that they are going to tire later on in the game.

"They put a huge amount of effort in against Inter Milan so there will be some physical and mental fatigue, so we have to make sure we are in there with a shout for the last quarter of the game.

"Chelsea have had a massive kick up the backside and didn't expect to lose that game and get knocked out of the Champions League, and they are now a wounded animal that you have got to protect against."

Allardyce has taken some tips from Mourinho's book of tactics by studying the success of Inter Milan -- and Wigan earlier in the season -- to pinpoint weaknesses in Carlo Ancelotti's side.

"I learn an awful lot from every game; I usually used to manage to set out a team tactically against Chelsea that could get a result and we have had a look at some of the stuff that Inter did," said Allardyce.

"We've also looked at what Wigan did when they beat them, as they are a team very similar to ourselves. If you watch Inter Milan's workrate and the tactics that they put together it shows why they nullified Chelsea so much."

Ancelotti has told his squad to focus on becoming only the seventh club in the history of the English game to achieve the league and FA Cup double. The Italian has handed the new challenge to his players in the wake of their disappointing Champions League exit.

"It's to put a new motivation in all the club," said Ancelotti. "To shift the objectives because we were focused on the Champions League and now we've changed our aim."
