Is there any physical/conditioning reason to be playing him a full 90 mins?
In my mind we’d be better off rebuilding him through concentrated minutes (45 - 60 mins). I see a player fully aware of (relatively) newfound physical limitations, and low in confidence on how to adjust his game.
I get that his speed may be gone, and perhaps his quick twitch, but I’m really alarmed that his finishing/chance creation is degrading too.
