Some of it is down to tactics.
It was clear he was pressing high up the pitch, at times higher up than Watkins. Constantly made runs in behind Watkins and took up positions as a striker throughout the game.
It's unreasonable so expect him to contribute too much further down the pitch when he's been instructed otherwise.
However the pressing seemed half arsed, never close to getting the ball, getting a foot in or getting physical at all. It looks more like pointless running then pressing. He's completely switched off as soon as we drop down defending deeper. If you compare him to any of our other attacking players they all track back to put in tackles or cover runs when we're under pressure, he just doesn't.
Added that to poor form going forward. I don't see there's anything justifying giving him a starting spot.
