That's an extremely high bar to judge him with, I can't think of anyone, maybe other than Messi, who would make that Spurs squad title contendors. I believe he is a striker who would have the same impact RvP did, make us legitamite title contenders in domestic and European competitions. Of course, that is contingent on City having an off season, would not expect us to have a 90+ point season to beat City if they are at the top of their game.
The squad comment can go both ways, while I would argue that our starting XI is as strong, if not stronger, than Bayern, I do agree that their bench strength is currently better than ours. That being said, with Kane I think our starting XI will be much better and maybe overall squad as well.
