I assume you mean Mitrovic? Who had more touches and won more headers in 13 minutes, than Cisse did in 60'?
I'm not disagreeing with you ffs. There's just a chance he won't be the answer. The sooner we find out the better obviously.
But overall the squad isn't where it needs to be. Any manager will make mistakes, especially a bang average one. I'm sure Cisse is for the hook soon, Obertan too. It's that midfield and Colo that I think might take a long time.
You said yourself it's difficult to take Cisse out when the replacement is an untested kid. Yet the untested kid performed better in 1/4 of the same pitch time. Doesn't sound like a difficult choice at all.
Nobody on this board could make a case for not bringing Mitrovic into the team at any point. Yet here you are.
