Former Arsenal boss Arsene Wenger admits Serge Gnabry doesn't have any weaknesses in his game, but questioned the German's attitude.

The pacy winger scored a brace against Chelsea in a 3-0 victory for Bayern at Stamford Bridge on Tuesday.

Wenger was manager of Arsenal when Gnabry was sold in 2016, and he still has questions over the Germany international's commitment.

"This guy has no real limitations," Wenger told beIN Sports . "It's more about how much does he want to suffer?

"He has pace, power, technical ability, he is very intelligent but sometimes he looks for the easy way. That was his problem.

"I sent him to West Brom and it didn't work out at all. In fairness, I think we had an agreement with him and Bayern stole him away from Bremen.

"He is a good player. He has individual ability and collective ability."
