The window is open a week, he isn't even at the club, the only offer that we are aware of is from Brighton (again, not Barca, and someone of a level I'd assume we can get an equivalent level loan for him from).
I don't believe in player loyalty because clubs will do what suits them, and yes, he should look out for his own interest, but he is making a lot of noise very early from not what I would consider a position of strength, no point arguing nuance of how professional/unprofessional it is, but it's hardly a good look for either party.
