If he does leave, Good riddance. Couldn't give less of a feck. There's a reliable article somewhere as people mentioned stating that he spent most of his time last season enjoying himself in Germany while sidelined. The same article states that that didn't bode well with the players back home, and rightly so. Furthermore, it seems a bit funny to me he spent most of the season on the sideline for us and then was in top shape all of a sudden for the euros. It's quite clear his priorities lie elsewhere and we don't need that kind of player here, regardless of status. The Shaw interview where he doesn't even mention BFS further confirms this for me.
To me it sounds like Mourinho has had a word with some of the senior players and the topic of BFS and his poor attitude last season must have come up(most likely with Rooney/Carrick)and has decided that due to this and his injury problems on top of that, he is not worth keeping for another season. It's funny how his brother complains about no respect but at the same time all signs point to a lack of respect shown by BFS to the club and the players last season.
If the above is legit, and reading between the lines; it seems to be the case. To me, this decision(if true) to banish him to the makes perfect sense and Mourinho acted in the correct manner. A lack of respect will be responded to with a lack of respect. Don't see what some are moaning about. Anything to bash Mourinho with, I assume.
