Good lad, I've liked Berahino's attitude in recent times, and think that Tony Pulis has managed him very well. I think Berahino needs people like Pulis who can support him and be genuine, it's a good move.
If Berahino does want to move, and does it in a respectful manner then you can't really criticise him. I hope he doesn't tarnish his name if he does leave, and hope he continues to mature.
