AS Monaco striker Dimitar Berbatov took a swipe at Arsenal's players after last night's Champions League shock.
The Gunners fell at home 3-1.
Berba said: "It's not good from their side to think like that because if you are a professional football player you don't need to underestimate anyone and if you show that then you'll get punished.
"We didn't let Arsenal play the way they want to play, we pressed them at some points and we were pretty well prepared. Not many people believed that we can do something but in the end we fully deserved the win we achieved today."
