LAURENT BLANC last night warned his players to expect dirty tricks from Diego Costa.

Jose Mourinho hit back at the Paris St-Germain boss claiming Blanc’s team are the roughest he has faced this season and dirtier than a League Two side.
The French giants are at Stamford Bridge tonight with a place in the quarter-finals of the Champions League at stake.
But a war of words erupted after Blanc claimed Chelsea hardman Costa is the man to watch out for.
“He’s a boy who loves the contact, loves the duels, and is very suited to the English game,” said Blanc.
“He likes the challenge, the contact, and provoking opposition players.
“That’s something he needs. He thrives off that. It’s important not to get caught up in that.
“I watched the game against Tottenham and, right from the start, he was looking to do that.
“He’s got good physicality, is technically good, but he tries to provoke a reaction always.
“Away from home, we have to be as effective as possible in trying to stop him.”

    

Mourinho refused to respond directly to Blanc’s attack on his star striker, who was banned last month for stamping on Liverpool’s Emre Can.
Instead he claims PSG showed in the first leg they take no prisoners.
Chelsea star Eden Hazard claimed after the 1-1 draw he needed shin pads to protect all of his legs after being roughed up in Paris.
“I was surprised in that game,” said Mourinho. “Because a team with fantastic players was the team with a record number of fouls.
“It was the team making foul after foul, it was the team which stopped Eden Hazard with fouls all the time.
“It was the team attacking the man in possession of the ball with two or three players with some very aggressive actions, a team where – even a player like Zlatan Ibrahimovic, a typical attacking player – came back when they lost the ball and attacked Hazard from behind when we were countering.I thought an English team would never be surprised by aggression, because aggression we have in our country.
“This season we’ve played against sides form the Championship in the cups, against teams from League One, and Shrewsbury from League Two, but the most aggressive team was PSG.
“With players of such quality, I was expecting more football and less aggression.”
Mourinho also dismissed the impact of moneybags PSG offering their players a £180,000 bonus to beat Chelsea.
“Professionalism goes above and beyond that,” he said.
“In many areas of society you reach certain objectives and people get extra payments, reaching some targets or numbers.
“That’s fine, but football is about our passion for the game, the happiness and the pride of victories. They have no price.”
