May well be having doubts now, when Bruce first enquired he may have thought, "ok i'll give it a try, i'll be the big cheese there, certain to start eveey game etc."
But now we have new recruits in the squad, things won't be as easy, no automatic choice for him. Maybe a little dent to his over inflated ego.
Maybe he will just be content to warm Man U bench as opposed to ours. Or someone else will take, as he is a decent player and will do a job somewhere, will it be at the SOL, only time will tell.
Another case of if he comes he comes, if he doesn't "C'est la vie".
