I'm going to be contrary. I thought he definitely showed what he is capable of but he also showed why he shouldn't play that far forward. His finish when he had a clear sight of goal was dreadful, he didn't seem to know how/when to make runs in behind and positioning when balls were put into the box was poor. All the good stuff he did today was as an attacking midfielder rather than as a striker.
I still think he could be really good in a 3 and I know we don't play it but if we played with 2 holding midfielders and one advanced then he'd be great as the more advanced of the 3 behind 2 strikers.
