Wenger might appear tactically inept, but he's certainly no fool. I believe he's gotten it right with Theo. For sure, Theo's a good finisher, but I don't think he'd be as effective if used as a CF/striker. I say this based on his less than technical attributes - one on one situations and all.

He gets into good scoring positions because he's able to swiftly get himself in and out of the box from that right wing. Make the mistake of stucking him into that lead striker's role, with one or two tall and/or physical defenders marking him for 90+ mins, and he'll probably look less than ordinary.

Theo has the pace similar to a TH14 but not the physical presence, trickery and raw power. He also has the stature of a Iceman, but not the def touch and sublime finish.

A good wing man he is and Wenger knows this as much as anyone else.
