LUIS ENRIQUE has told his Barcelona stars to keep their cool tonight when they defend a 3-0 advantage in the Champions League semi-final second leg at Bayern Munich.

The Nou Camp side gained the upper hand with three late goals last week, Lionel Messi bagging a double before Neymar struck in stoppage-time.

But the Barca coach is aware the Germans are far from beaten. Enrique said: "We don't want to have a crazy game and if it is a crazy game we will have to calm it down.

"We will try to do it with counter-attacks. We want to have the ball, we want possession. It will be difficult because Bayern will do the same thing. But we will try to find the spaces and score goals."

Bayern have twice crushed the opposition in home Champions League games this season, thrashing Shakhtar Donetsk 7-0 after a goalless draw in Ukraine in the round of 16 and then demolishing Porto 6-1 after losing their quarter-final first leg 3-1 in Portugal.

Against Porto they scored five times in the opening 40 minutes to kill off the tie and that is what Enrique is desperate to avoid.

He said: "You should not be too confident going into a game like that. You have to respect the opponent, calm your players down, control their emotions."

With Bayern on the back foot, the Germans will be looking for an early goal that could pave the way for memorable comeback against arguably the most in-form team in Europe.

Enrique knows Bayern coach Pep Guardiola, a former team-mate, will not have given up hope.

The Spaniard added: "He will try to have possession, to create chances and be strong in defence. I expect an attacking Bayern and we will do the same thing."

While Bayern have struggled in recent weeks, Barca are on a high after all but securing the La Liga title. They have also scored 25 goals in their last seven outings.

Midfielder Javier Mascherano said: "We will attack. We don't know any other way to play, we don't know how to play a defensive game.

"That is the philosophy of our club. Obviously we have an advantage, but we will try to find at least one goal."

Guardiola, meanwhile, is determined to honour his contract with the Bundesliga champions.

Reports in England over the weekend claimed he had agreed terms to replace Manuel Pellegrini at Manchester City.

But Guardiola, whose current deal expires next summer, has brushed aside such speculation and claims he has no plans to leave the Allianz Arena any time soon.

He said: "I have a contract and I will stay here at Bayern. That's all."

Guardiola joined Bayern two years ago after enjoying incredible success with Barcelona, first as a player and then as a coach.

The 44-year-old won 14 titles - including two Champions League crowns - in a trophy-laden four-year stint at the helm of the Catalan giants.

Considered by many of his peers to be the world's best coach, he has followed his success at Barca by winning back-to-back Bundesliga titles.

But despite that, and the speculation that City want him, Guardiola is unwilling to talk himself up.

The former Spain international said: "To be the best coach in the world means nothing. I've said it a million times. I win because I have great players."
