I wouldn't expect any player to immediately hand in a transfer request after being warmly welcomed, awarded and them waxing lyrical about what a great year they've had. Badly advised or not, he could have remained impartial publicly whilst this transfer business was conducted.
He’ll have been advised by his agent, who undoubtedly will have told him that if you don’t do this you’re in danger of losing the move. I very much doubt he did it with any malice or disrespect intended. I’ve seen nothing bad from him personally at all, I wish we’d had another couple of seasons with him in the squad but I’m not going to get offended by him daring to want to double his wages and play in the Champions League.
I will miss him, and wish him and his family all the best. (except when he’s playing against Brighton of course, then I hope he keeps stepping on rakes)
