#1 Poor results
Mourinho faces an uphill task to deliver good results in the coming months on a consistent basis because the fans and the United leadership demand it. Any major slip up over a spell of five matches and there is the sense that his luck would have run out.
As it is right now, United have been inconsistent in the season and are yet to face the big boys. United slid back into the usual uncertainty after failing to beat Wolverhampton Wanderers at home. This is a major concern for Mourinho.
Before Christmas, United still have to play the other top six sides on top of battles with Juventus in the Champions League. Mourinho will most certainly be monitored on how he negotiates past those tricky waters but the chances do not look so good all factors considered.
