Possibly mate but the likes of Dier and Mustafi are the classic one that got away type scenario and left without any fuss, expectation, local boy pressure, media scrutiny, had minimum exposure to the first team etc. Lots of top players started somewhere else.
Rooney had already convinced everyone he had it and it was all about the cash and the state we were in.
Ross is yet to convince everyone and I think with him being that bit older than the likes of those we mention above when they left and with the impact/influence of the issues I mention, his situation is subtly different.
He could walk and it might be the making of him - he could equally fall on his arse in a big way and become some sort of journeyman - I suppose time will tell.
