This is a key point. The way we've played, our main striker has ro work their balls off and cover a lot of ground.
With Bruce they were isolated and had do lots of running to any kind of sniff of the ball.
With Howe, they have the high press aslo demanding a high work rate.
It's a lot of work required for a striker to play in either system. Wilson probably knackered himself more from being our only real choice up front. Wood is doing the work now (I'm not getting I to how effectively as that's a different conversation that has been well covered elsewhere).
My point is, with more options up front, we won't need to knacker our main striker out.
Wilson could probably go a full season if hes mainly coming off the bench for between say 15-30 minutes most games.
