Its funny and kind of ironic, Firstly i think he has played well this season not amazing but well and in some matches and brilliant in others. I believe he gets unfair criticism all the time. He plays and gets criticized for passing sideways and backwards when he helps us control the match, i don't think we were this bad this season in any match with Herrera playing (in fact we were better Benfica away in which he started they hardly created anything). Now when he does not play and Benfica dominate us and is unlucky not to score until his introduction (after that which we were the better side and controlled the game to finishing line). Just maybe just maybe our lack of attacking threat and poor style of play is due to not having a Right winger or our inconsistent but brilliant Rashford/Martial or our no10's shitting themselves and not keeping hold of the ball and loosing it every second or Lukaku who can't trap a bag of sand at the moment? How any any fluid and attacking play be constructed among these players? and When people run out of people to criticize and pin blame on them Herrera gets in the firing line.
I believe with Pogba and Zlatan coming back we will become a better side to watch, since they have the ability to actually control a pass and play quick one touch football and receive a pass under pressure without shitting themselves. Then when the attacking play will be sorted out, people will appreciate the defensive stability and control to the match he brings, and for those who are awaiting Fellani's return trust me you will be disappointed, he is a good player for a particular system but keep the same lineup and change Fellani with Herrera and we will actually become worse to watch, although we might score on one or two crosses.
