I wouldn't want a centre forward checking back in that position. Would only have to try and get a shot on goal, with their momentum heading away from goal. I want a forward to be in position for a ball played across goal, which is what he was. Or somebody arriving late into the box for a pull back, which nobody did.
Yeah, Sibbick might've been as well just firing it towards the far post once he'd taken the extra touch, and Cole would've been there or thereabouts for any rebound if the keeper saves it.
