He is going to be successful there. Spurs have a good squad that would suit him. He doesn't even need to spend a lot, and if there's any manager capable of getting the best out of a decent squad it's him - he has shown that at previous clubs at least.
He will have the perfect striker to call upon, wingers that excel at both ends, experienced defenders, midfielders that would run all day, and hardworking AMs capable of magical moments. I think the biggest challenge would be getting the likes of Alderweireld, Vertoghen, Kane, Eriksen, Lo Celso to stay and perform if they've still got it. I desperately want him to do well.
