I also said the same before, specifically for Mkhitaryan and was called hater.
This is Inzaghi's flaw since he came at Inter, and this season he has some improvement in that aspect and let's hope to keep improving in future as well.
I really hope him starting to rotate more till the end of the season, considering our comfortable lead. Players like Asllani, Frattesi, Buchanan and Bisseck shall play much more. Maybe it's good to try some experiments like deploying Pavard as CB or Asllani as mezzala. Frattesi shall start every match to build up confidence with Barella and Mkhitaryan sharing the other spot.
But he will try to break Jube's points record most probably, playing the starters every match no matter what.
