I just don't like watching him play. He's on the floor all the time forcing the game to stop, or moaning at the ref, or trying to con cheap penalties. He's never actually won anything so I don't really get what the point of any of it is.
He had the thing at Tottenham where he'd take all their freekicks despite being laughably bad at them, because (I can only guess) his ego was too precious to leave them for anyone else...and mysteriously Tottenham suddenly look like a football team again without him, having spent the 5 years prior gradually turning into an enabling resource for Kane to do whatever he wants.
He went on TV and did an interview with Gary Neville about how he wanted to leave Tottenham, while still at Tottenham, and being paid by Tottenham, and then ended up not leaving Tottenham that year, and then the media had to try and paint it as "Professional" behavior because he's England captain.
I just think he's a bit of an idiot.
Maybe being surrounded by players who are more interested in winning trophies than how many goals Harry Kane scores will actually help him realise that he'll still score the goals regardless.
