The German has admitted his Leeds side can do better.
Indeed, Rosler's men did what they so often haven't done this term, grinding out a result despite not looking good value for it.
And, while that naturally pleased the Leeds boss, he says United have certainly played better so far this campaign.
The German told BBC Radio Leeds: "I'm sure we've had better games and better periods in games. The last 20 minutes was a panic, I have to admit that.
"We have to keep the ball better and keep it with a purpose, like we did in the first 15 minutes."
After the win against MK Dons, there was certainly plenty of concern in the comments section on HITC Sport, with supporters criticising United's performance in Milton Keynes and suggesting they were more than lucky to win.
Considering Leeds' slow but steady start to the Championship season, it might seem a tad dramatic to be predicting major issues at Elland Road. But it seems those that watch the games closely aren't happy with the Yorkshire side's performance levels - even though they have now won their second game of the campaign, only losing once so far this term.
The question is whether Rosler is building towards something where Leeds can convince with their performances and not simply hang to get their victories.
