One the other hand he's a model professional and isn't going to embarrass any brand associations by getting into fights at a nightclub, or getting caught drink-driving. His current brand associations include Nike, Beats By Dre, Lucozade Sport and BT Sport.
Sports pro say he's the 20th most marketable person in sport globally. That's across all sports, not just football: http://www.sportspromedia.com/most-marketable/2017/harry-kane-2017
Possibly, but I don't see him appearing on TV adverts selling Boxer shorts anytime soon.
I can't emphasise enough how much I rate the kid so I'm not being mean. He's just a bit James Milner in terms of excitement. Think of Spurs players that are exciting and you'll name Alli, United Pogba, Liverpool Coutinho, City Aguero, Arsenal Sanchez etc etc. They all have that glamour, Kane doesn't have it. If he did he'd be up there when people mention world class strikers. At the minute people still say he has to prove himself. Like he hasn't already?
