So far, he is more Moyes on steroids, than a really top manager. Most of the arguments here have been used for Moyes too when we hired him. Punched above his weight, net spent, gets the best out of his player, gives chances to youth players, builds a team and so on., failing to understand that not winning a trophy in 11 seasons is far from justifiable if the manager is really a top manager.
Now, Pochetino is a far superior manager compared to Moyes. He does everything better than Moyes, there is no doubt there. This is also just his fourth season at Spurs, so we should probably be a bit patient on judging him. But in my opinion, the time is running out for him to win a trophy if he wants to really be rated as a top manager, and either then constantly win trophies, or go to a club which gives him the platform to do so.
NB: A better comparison to Pochetino would be Spalletti. Like Pochetino, he did good recruitment, played good football and built teams better than what they should have done with their resources. However, he never managed to crack winning trophies. I made the comparison with Moyes because people here are more familiar with Moyes, and because Spalletti actually managed to win Coppa Italia twice.
