If its someone like Bellerin I'll offer my services to hold the door firmly closed.
If the reports are true and he does feel this way there's no reason to think that after a successful or even promising season under a new manager he wouldn't change his mind.
He's just signed a six year contract so it's not like either him or Barcelona have enough leverage to make the move happen anyway.
The only way he leaves is if we get a good enough offer to convince us. In my eyes that has to be at least £40m.
