He's a young lad with plenty of people in his ear. Make no mistake if he stays and Martinez stays his career is going nowhere and he'll have been told that repeatedly. As things stand he could well be a bit part player in the Euros because of this season.
If he is prepared to issue demands about the manager then its because he wants to stay and be successful here, otherwise he'd ask to leave or turn down the contract offer.
Not excusing players not making an effort this season, they do need to take a good long look at themselves including Ross.
