He is a much better coach than Rodgers. Probably not at Conte/Pep/Klopp-level, but Spurs was a very well coached side. They was well organized and he took several of their players from looking average/poor to top 4-material. Imagine Spurs being regular in top 4 and making a CL-final!
I would probably argue that it is easier being at Leicester too as they recruit very well. Spurs generally dont.
Rodgers was a good coach in 2014. The benchmark then was Pellegrini, Mourinho, Wenger and Moyes. Other teams had Allardyce, Laudrup, Hughes, di Canio, Steven Clarke, Hughton, Pardew, Jol, Holloway, Mackay and Lambert. The benchmark today is Klopp, Conte, Pep, Tuchel. Midtable teams employ Bielsa, Hassenhuttl, Moyes, Benitez etc.
