Bayern Munich defender Jerome Boateng has warned his team-mates not to underestimate CSKA Moscow ahead of their Champions League encounter.
The Germany international admits that he does not know much about the Russian champions as of yet but knows that Tuesday's game cannot be taken lightly.
"They have a couple of really talented players, so we can't underestimate them. We have to be careful," Boateng told the club's official website.
"We don't often get to see CSKA's games, so it's hard to say what we can expect. We'll be taking a look at a lot of video material and I'll personally check out their strikers online.
"What I do know is that they're very tricky opponents."
