Lionel Messi said Barcelona will give their all in the second leg of their Champions League clash with Bayern Munich tonight, despite having established a virtually unassailable 4-0 lead in the first leg.

Not even Bayern coach Jurgen Klinsmann expects his side to be able to come back from such a deficit at the Allianz Arena but Argentina forward Messi, who scored twice in the first match, is still urging caution.

PREPARED: Lionel Messi

"We cannot go into the game believing it is already over," he said.

"They are a good team and have good strikers who are strong in the air. The only thing we can do is play as we always do."

Barca coach Pep Guardiola is set to resist the temptation to field a weakened side for the game, insisting he cannot take any risks in Germany.

"We have an advantage of four goals, but we have to maintain concentration as we still have to play this game," he said.

"The fact that the first leg went so well does not mean that the second game will go so well.

"We still have got to play this game and we have a great advantage, but that does not give us any right to believe that tomorrow will be easy.

Klinsmann promised to attack from the off and give the fans at the Allianz Arena something to cheer about and Guardiola is ready to fight fire with fire.
