we had a good discussion back in April about this, just as he was approaching 20 goals, and he scores a lot of close range goals, nearly every single one of which is a first touch, snap shot or header.
Today he played well for the team but he came too deep too many times. Sometimes his feet let him down when he has too much time to think and you saw three times he gave it away cheaply.
He played well but for me he is primarily an out and out striker and he will not score many goals unless he permanently hangs around the centre half and gets in the 6 yard box for tap ins.
