I didn't exactly follow Mino so I don't have the answer for it.But Hamsik is not doing worse is it?So did Insigne.
I think the issue is you want to believe that your Donnarumma loves Milan more than anything.I also do believe that he also loves Milan but above all else? Hell No!
What my takes on Mou that you don't understand?Off course he is right and I give you my thought on example with De Light and Donnarumma on why they keep obeying what Mino said compared to Zlatan.
On Zlatan,you are wrong, Man Utd is also interested on him so you can't said that his move here is sort of desperate move.
I dunno about Donnarumma but if he wants to leave Milan it's his decision.It won't stop Milan being back to be a great club again
