The two managers clashed after Peters celebrated his sides last gasp winner by running through the Wigan technical area.
Speaking about the incident Rosler said: "My colleague was running 25-30 metres to celebrate right in front of our bench and I told him what I thought about this.
"It's not only the timing of the goal, it's a deflected goal. I felt for the first 30 minutes we were in complete control and passed the ball well. We could have created one or two bigger chances.
"Their goal came against the run of play, but we responded well through Callum. In the second half there was nothing between the two sides and the goal was cruel."
The Latics now face a tough test to face Cardiff City on Tuesday evening before Blackpool come to visit the DW Stadium on Saturday.
