Mourinho, now at Manchester United, has taken that mentality to Old Trafford with the Red Devils unbeaten from their three league games so far this season.
And Cech has admitted that killer mentality is missing from Arsene Wenger‘s Gunners.
“He brought the same spirit in Chelsea. He thinks only about victory, whatever the price.
“He hates draws. If we returned to the dressing room with a draw, it was known that he would not be satisfied.
“On the other hand, he also wanted be able to keep a 1-0 or beat a team 5-0 if possible. No matter how, Mourinho wants the result.
“The philosophy at Arsenal is completely opposed to this: it is not win at all costs but we want to win with a good way of playing. This is beginning to change in our approach.”
