Leeds United head coach has once again re-affirmed his stance that the club's best players will not be sold.
Questioned regarding the future of talented prospect Sam Byram, Rosler has in the process backed the club's owner into a corner over the issue.
Rosler told SkySports: "In all the talks I've had with Mr Cellino and Adam Pearson, we don't need to sell at the moment.
"We are on an even keel and through the efforts of Mr Cellino we can pay our bills and we don't need to sell to pay our bills and that's all that I can say."
The German went onto make clear that he sees Byram, along with young talents Lewis Cook and Alex Mowatt as cornerstones of the club's future and has no desire to sell any of them.
If Leeds were to suddenly accept a big offer which came in for any of the players now, the spotlight would be firmly shone onto the owner, to ask just why his mind has seemingly been changed.
The Italian is clearly not scared of making unpopular decisions as he proved by his treatment of Neil Redfearn at the end of last season, but to take a view to sell one of the club's exciting youngsters would be a terrible short-term solution, and one which in the past did not pan out, with Fabian Delph and James Milner two examples.
Rosler began his interview by stating Leeds had not yet received any firm offers for Sam Byram, despite The Mirror reporting last month Sunderland were to submit an offer in the region of £8 million.
Which means Leeds' not-for-sale stance has been theoretical up to this point, and has not been put to the test.
When it is, which inevitably will happen at some stage unless clubs are really put off by Rosler's comments, owner Massimo Cellino has been nicely put under pressure not to bow to any financial temptation, and see the head coach's promise through.
