Bayern Munich midfielder Toni Kroos has warned teammates not to allow Champions League opponents Arsenal make them look "stupid".
Kroos admits his team will be completely "stupid" if they crash out of the Europe to Arsenal.
He said: "It is extremely good to be 3-1 up ahead of a home game but it will not be easy as Arsenal are a very good team.
"But we will be really stupid if we go into this game with the wrong attitude and then give it all away and fail to qualify.
"I hope this does not happen."
