You ever read The Rime of the Ancient Mariner? Kane is for sure the Albatross of the story. I'm a total casual fan because my wife follows them and so I watch them. I like them so much better without Kane. I wish them the best, until it comes time to play Liverpool.....
He wasn't clearly the issue. He's been doing well at Bayern with a team only partially built around him. He probably wouldn't have be the best fit under Ange, and perhaps we wouldn't be doing as well, but he wasn't THE problem at Spurs. Perhaps symbolic of many of the problems that have dogged the club since Poch's peak. Arguably a case of Ewing Theory.
I'd put the main issue down as Levy neglecting the football in favour of the business (the stadium etc), then seeking quick fixes when things turned south. But with Scott Munn coming in to take over running the football side, along with Ange as coach and Lange as scout, we could have reached a turning point. Time will tell.
Weren't a joke under Poch - Levy just didn't invest in new players and burnt that squad and the manager out. A few years in the wilderness with the wrong managers was the worst thing that could have happened. But here we are with the right manager now, back as a contender.
