The Latics edged the Capital One Cup winners 2-1 at the Etihad Stadium to book a place in the final four of this season's competition and Rosler said the victory can be put down to Martinez's side who beat the Eastlands outfit in the final last campaign .
"I started with Roberto's tactic from last season," said Rosler.
"He won the FA Cup by putting out a very brave game-plan and also I saw the league game here (against Wigan last April) where Manchester City won in the last five minutes 1-0 and Roberto's team played periods to perfection.
"I tried to replicate parts of it but bringing our own intensity in terms of our pressing, our counter-attacking and the willingness to attack with wing-backs at the far post - like the second goal.
"I felt first half we surprised Manchester City because a lot of teams show Manchester City, deservedly, a lot of respect. I felt if we sat back and just tried to defend and just hoping for the best we would have no chance."
Jordi Gomez netted from the penalty spot in the 27th minute before James Perch added a second early in the second half prior to Samir Nasri's 68th-minute consolation, allowing Wigan to set up a semi-final date with Arsenal.
