I was thinking the same thing, he doesn't seem the type. I can't see it because of his reaction at the end of their game as well; it seems more like a deal is a lot further down the line so a transfer request won't be needed.
If Lescott was to blame for something then quite rightly his team mates bollocked him, that would have happened whether he'd handed a transfer request in or not.
I hope they're right, Taylor would be an excellent signing and he's in the Jagielka mould (i.e. a real defender who throws himself infront of everything).
