The Leeds United boss has been talking about his team's latest setback.
Leeds went behind when Solly March scored for the visitors but defender Liam Cooper equalised just eight minutes later.
The score remained 1-1 deep into the second half but Bobby Zamora broke Leeds hearts with an 89th-minute winner.
Leeds striker Chris Wood had a wonderful chance to score what could have been the winner, but the New Zealand international inexplicably headed over from just six yards out, and after the game Rosler identified that as one of three key moments.
Explaining that the first was when Brighton scored from their very first attack, Rosler went on to tell the YEP, “The second key moment was when Chris Wood didn’t take his unbelievable opportunity.
“The game looked like ending 1-1 so we brought on Mirco Antenucci and Will Buckley to try and win it but the third key moment was Liam Cooper’s injury, leaving us with 10 men.”
That final blow meant Leeds ultimately conceded the winner and left Rosler’s side with plenty of work to do in the weeks and months ahead.
This Leeds side certainly has the talent to succeed in the second tier but for now they are simply not getting the luck or showing the killer instinct required to beat the teams around them, let alone those riding high at the top of the division.
