You don’t believe Mase can become a world class striker?
As for Kane, I think he’s a brilliant striker, although like most players, not perfect. His performances at the Euros so far are not surprising to me, for instance. I see them as relatively typical Kane performances when he finds himself in big games or against difficult teams/opposition. That’s his average performance level vs United, with the exception of the odd game where we are going through a spell of being shite and are massive underdogs against Spurs. What often happens is that he’ll go and score 4 against Sheffield United the following week though.
Think you're assessing his performances too much on the games against United. His performances in big games are fairly solid, and his record against the top 6 is pretty good. If I remember correctly the two clubs which most of his goals have come against are Leicester and Arsenal.
