Still think more time needs to pass before we can call him that. Winning titles in what was basically a one team league is one thing. Celtic did nothing in Europe under him.
He also did very well with F Marinos, in a very competitive J League, which was impressive but also Marinos are traditionally one of the biggest clubs in Japan.
Give him a season at Spurs. They've played a couple of games.
One thing is for sure, he's a motivator.
