Drogba has gone and Chelsea are now following Wenger's own template of creative midfield players and strikers, which should make for an intriguing clash at the Emirates.
Wenger believes the likes of Juan Mata, Eden Hazard and Oscar have brought panache rather than muscle to Stamford Bridge.
"When you think about them, they had Florent Malouda, Essien, Lampard, physically, contact-wise they were a very impressive side with Drogba on top of that," the Daily Express quoted Arsene Wenger, as saying.
"They wanted to change their style and maybe there are not the same players available now on the market," he added.
"That Chelsea team won the Champions League, and you have to give them credit for that. With those players and Ashley Cole, John Terry and Petr Cech they have gone through thick and thin in the Champions League; but in the end they managed to do it because they accumulated the experience and efficiency," he said.
