The French club sprung a surprise on the Gunners with a 3-1 triumph in the Champions League Round of 16 first leg at the Emirates Stadium on Wednesday night in a performance losing manager Arsene Wenger described as 'horrible'.
Former Tottenham forward Berbatov, who fired home Monaco's second goal early in the second half, said Leonardo Jardim's outfit had identified Arsenal's slack defending as a weakness of the north Londoners and went about manipulating that in order to achieve such a positive result.
"To be honest, we were not surprised," said the 34-year old Bulgarian ace.
"Arsenal have very quick players and when they go forward they leave a lot of space at the back.
"We knew that and we had prepared well and took advantage of it. We knew their weaknesses and we exploited them and I think everyone can agree that we deserved our win.
"Our team is very young but very talented. It is not only about age but about class. If you prepare well and do what your coach says, you can see the result. We believed we could do something. This is for everybody."
