Of course, the new Sporting president is no Saint either. Most players are being tied to the club with unrealistic release clause while being paid peanuts. He does not respect what the players want, and only care about what's good for himself and the club. Furthermore, he will go to the media and paint the players who wants to leave as traitors and terrible human beings. They made Dier looked awful in the media and the fans hated him, now he is trying to do the same to Rojo.
Carvalho is another one, and with Doyen owning 40% of his rights (funnily enough, they only paid 400k to get his 40%), I doubt it will be easy to get him as well.
