He's 22 - are you seriously saying you are writing off his abilities based on 160mins of PL football? Wow.
I remember people doing that with Rose, Kane and Lamela.
The guy has been tracking back to our own half to perform great ball winning tackles, can hold the ball up, ha shown great awareness - but you're saying he's not gifted, despite the fact that he has the likes of Eriksen and Alli behind him, who are currently (on present form) ballooning shots into the stands instead of creating chances. Kane's passing has been statistically awful as well, so I don't know how you're expecting him to see any of the ball to show what you're judging him on.
