Has he?
Over the last two years :
Herrera 13 goals and 11 assists.
Fellaini 11 goals and 2 assists.
But Fellaini's goals include the following:
-The goal to seal UCL qualification against Palace.
-The goal in the derby against City(which at the time meant we went into the lead, and at that point where 2nd in the league)
-goal in the UCL qualifier in the 90th minute meaning that we had an easier 2nd tie rather than being under pressure going in with just a 1 goal lead.
- A goal in the Quarter finals of the fa cup.
He tends to perform when it really matters. For a side that rarely scores, that has been a positive for us big time. Yet people simply refuse to see that, or when they do give him any compliment, its always the "he did well, but..(insert whatever Fellaini cliche'" here)
