I think its fair to say that Alfie has never been a top finisher, even given the number of goals he scores. He doesn't tend to strike the ball very true, often snatching or sclaffing it into the ground, making him look really average when not on form. His performance on Saturday was the perfect encapsulation of this
His main strength is the ball being played into his feet and him turning the defender and getting a shot away. He has been dropping too deep to be fully effective, although the number of chances he got on Saturday might be an encouraging sign of him getting into better positions
I do think he needs a period on the bench though
