The German, brought to fill the vacancy from Brentford just eight days ago, is keen to instill a high tempo, high pressing ethos in Latics' ranks and the opening half an hour here followed that blueprint perfectly.
However, Wanderers clawed themselves back into the game and after Neil Danns and Andre Moritz, from the penalty spot, had brought Dougie Freedman's side level, Callum McManaman's strike was required to give Rosler the perfect DW Stadium start.
"I don't like so much excitement," he said of a pulsating north-west derby.
"The team responded very well to the tactics we have set out, pressure high, pressure all over the pitch, attacking-minded football.
"The first 35 minutes was very, very good; that's the way I want to play. The players were very good in executing that on the pitch."
It was fitting that McManaman should crown an inspirational performance with the winner as the winger, who Roy Hodgson is keeping tabs on for the England squad, terrorised Bolton left-back Alex Baptise all afternoon.
Rosler, though, revealed he almost left his star performer out of the starting XI.
He added: "I was thinking of not playing him from the start, bringing him on as an impact player. But he was so good against Maribor (on Thursday) I thought we need to build confidence with this lad.
"He is a match-winner for us; we just need to bring him on to a level where he can play 90 minutes with that intensity and that quality. We left him on and he will get a lot out of this fitness wise.
"On the ball, he's fantastic. He can destroy oppositions, he did it very effectively and to get the goal rounded up a very good performance from him."
