He is 53yo, with successful yet long, fatiguing, dedicated careers behind him as a player and a coach, and with a terrible last year from a personal perspective… so his latest rant does not come unexpected at all.
That said, he is past his peak and out of touch as a coach with new generations of kids and surely at fault (say, 1/3 fault… 1/3 for Levy and 1/3 the players) for not having won any trophy, which was his main professional intent at Spurs.
He is just morphing into late stage Capello, a stubborn, insensitive and pretty brutalist style of football.
