Bayern Munich midfielder Javi Martinez has warned teammates not to be complacent going into their Champions League second-leg clash with Arsenal.

Bayern will be defending a 3-1 lead at the Allianz Arena.

But Martinez says: "We need to concentrate for the full 90 ­minutes because to go out after leading 3-1 would be a huge blow for us.

"Nobody is thinking in this way but we all know Arsenal will arrive in Germany ­playing for pride and looking for revenge.

"We were superior to them in London in every way. Perhaps we didn't score enough goals but to annihilate a team like Arsenal at their home ground is never easy.

"I expected a better ­performance from the ­Gunners but we started the match like a hurricane.

"People have criticised their performance - but we totally ran rings around them."
