Well if he didn't play Fellaini who would he play? Like I said we're not blessed with options. He inherited a squad from someone else, just because he's given him a few games doesn't mean he rates him.
He could have played Schneiderlin or schweinsteiger if he didn't rate Fellaini. Fellaini played from the first game so it's not like Jose realised during the season that Fellaini was slightly better and started playing him. It was obvious from day 1 that he rated him.
