I think we should take a stand and not sell him this window, for any price. We should sit him down and explain that we will let him go for free at the end of the season, but have decided that due to Real's unwillingness to negotiate, that we have already included him in this seasons plans.
And before anyone starts with the "keeping unhappy players thing" at the club, this guys are professionals and will behave as such.Just a few examples of players that wanted to leave their clubs and were forced to stay
Luis Suarez: Denied a move to Arsenal, he turns around to have the greatest season arguably by any Liverpool player in EPL history.
Modric: After Spurs reject Chelsea's 40 mil bid and he being evidently unhappy, goes on to have a great season culminating in him getting a move to Real.
Scneiderlin : After Southhampton refused to sell him to Spurs, he goes on to have a great season there getting Southampton back into Europe.
I am sure they are many others. He's got Euro2016 next year, and will want to prove a point.
