I think Mourinho is a good manager, however I also think Rafa is a great manager.
We have Rafa (and he has already delivered on a number of things), we don't have Mourinho.
Mourinho will not want to be out of the CL next season, and it looks increasingly like we are not, given that we now need 2 clubs to slip up significantly. I am still hopeful but it is going to be very difficult.
