I'll never rate Kane for his individual achievements in the game because he's done feck all in terms of trophies. Rooney has had to sacrifice his individual numbers and accolades to adjust his game in order to win trophies. I have a lot of respect for that because I believe football is a team game.
Rooney often had to change his game for other players. The season after Ronaldo left, he put up prolific numbers. What happened that season? United won feck all. Just like Spurs with Kane. Maybe in a world where Fergie grew tired of winning trophies, he'd have decided ok there's no need to improve upon this, let's just have Rooney be the focal point and he can continue improving his individual numbers. But Fergie (and Rooney, it has to be said) wants to win trophies. If that means making adjustments at the expense of individual numbers, then so be it.
Kane should've moved 3-4 years ago to be honest. Just stopped signing contract extensions with Spurs. He'd have been hitting his stride in his peak at a serious club like Real Madrid, City or even Bayern Munich. I don't include United in that list, Spurs fans, just in case what I'm saying here rubs you guys the wrong way.
