If he's carrying a knock, and it's something that can get better with proper rest, it would be great to bring an experienced forward in early Jan, so we can take him out of the firing line and have him back firing in Feb/March for the run-in.
Only the club knows what he can/can't manage, but with the amount of player data they have these days, I can't imagine for one moment they can't see the on-pitch limitations he currently has. He needs help, he needs to sort his injury out - for him and for the team.
