He did that last season when playing that role. Get him the ball, when counter attacking or through buildup play. Spin, twist, physicality, passing, however. Turn decent possession where most players would play a safe pass into a line breaking move. He won't have to do that all that often to be a real threat in that role, and we know he's capable of that.
Even against Villa, even though he didn't have a good game in terms of delivering on what we want him to do on the ball he was a problem for them. A player they had to adjust to.
The difference between a long ball played because that's our only threat and a long ball played because that's the best option in a situation where the opposition have to be aware of different threats is significant. Not trying to give him credit for the chances we created where he wasn't involved, but I think having him in the team in that role makes a difference to our overall play, makes us harder to play against. And that will only improve when he has a good game on the ball.
The downside in that role is that he seems unlikely to be delivering a lot of goals. So would put the goalscoring responsibility more on Kane and the wide players. But his actual end product in that role is still somewhat unknown.
