The Whites welcome Carlos Carvahal's men to Elland Road in tomorrow's early kick-off.
The Whites boss previously complained about the fixture scheduling and is unhappy with tomorrow’s game being an early kick-off.
“The spirit is high in the camp and now we have to build the boys up again for Saturday because we play at 12.30pm – what a surprise that is ...” he said, in quotes published by the Yorkshire Post.
“On Friday, there will be very, very little training and on Saturday, we need our supporters.
“They need to push us in that game. This is the last one of four in 10 days and they need to really push us.
“We will make one or two changes and refresh certain areas and then we go again.”
Rosler’s frustrations with Leeds’ fixtures came to the fore after his side surrendered a two-goal advantage in the dying moments against Bristol City on Wednesday.
It was a game the Whites should have comfortably seen out, but instead leaves them searching for a first win after three successive draws.
Sheffield Wednesday travel to Elland Road off the back of a decent start to the season which has seen them pick up four points from their first three games, with their only loss coming to title contenders Ipswich.
Leeds on the other hand, have endured an underwhelming start to a campaign which began full of optimism.
The makings of a strong side are clearly present in Rosler’s team, but he is now tasked with getting the components to gel before slipping further behind the leading pack, and he will be hoping to that tomorrow's game proves a turning point.
