He appears to be a completely different player. He's always been a work horse but today he distributed the ball quickly every time he got the ball and played crisp passes that worked very well to draw Fulham defenders out of position.
Great job for his goals (i would give him the first one, it was on target and multiple deflections took it wide then back on course) and unlucky not to complete the hattrick when he hit the post. And while we've known he could poach for some time, his movement off the ball, passing, and anticipation were fantastic today.
I think he does very well next to Lukaku / in the hole, especially against tired defenders. If he keeps up this form he'll remain a fantastic option off the bench.
