My thoughts exactly.
The fact that he didn't stand out as amazing at any one thing is what made me unsure as to whether he'd make it at the top level at all. He's not all that big, all that strong, he almost looks clumsy when he takes someone on - the ball invariably comes off the defender at some point in the move. He's not graceful on the ball like Alli, whilst he can score from distance he doesn't hit them like Eriksen, he's not blisteringly quick, etc etc.
Yet pretty much everything he does is effective. He is on target with a ridiculously high proportion of his shots, he keeps posting huge shot per game numbers and we all know about the rate at which he scores.
