Leeds United have been guilty of giving away cheap goals on numerous occasions this season.
The Whites have been the masters of their own downfall on numerous occasions this term, and their frailty at the back was exposed against against Brighton & Hove Albion at the weekend.
The Seagulls were able to net a last minute winner through Bobby Zamora, and the ease with which they scored frustrated the German boss.
"The goal has come too easy," he said. "It's far too easy. We have to talk about that, for all the positives we had today, and for the good response. We cannot give away a goal like this."
Leeds ended up losing 2-1 to Brighton, and in doing so they set an unwanted club record of 11 straight games without victory at Elland Road.
The Whites' home form has been awful for a sustained period of time, yet they should would have accumulated far more points.
Rosler had shown his determination to change the path Leeds are on but the defeat against Brighton proved fatal for him as Leeds confirmed, as reported by the BBC, that the German tactician had been axed.
Leeds have often matched teams, only for individual errors to cost them dear, and in the end it seems that those mistakes cost Rosler his job.
Leeds have now won just one of their last six Championship matches, and they currently sit in 18th position in the table.
