Wants a long ban for this

I don't know. It looks like he is making a genuine attempt for the ball but is late. A ban for a red sure but a long ban would seem harsh. Especially when you consider what Musiala got away without even a red for in the World Cup and absolutely not retrospective action even though that was a downright attempt to do an opponent harm

 

I don't think he does it intentional though. He is closing down the keeper, certainly gets his timing wrong and I don't think he expects the keeper to roll the ball as far as he does and by the time he realises both his momentum is such he can't fully pull out. He does pull out of the tackle/block.

As I said its a red but certainly not worth more than the standard ban
