Tottenham's squad is not enough good, yet they perform well enough. They are not defeated by too many goals. Mourinho is a really great coach. He is able to perform well with a team that has almost collapsed. Liverpool has a lot of star players than Tottenham. Yet Liverpool are doing very poorly this season.
I believe its all about timing and performance. Its not about the players they have entirely or who have the better or compare it with the squad value, there are other things as well like strategy and so and so. In Spurs vs Arsenal , Spurs had a 1 goal advantage but their approach of letting Arsenal deep into defence and keep attacking them costed them. It was same with Zagreb, they let them keep on taking the shots. I think there are some approach that needs to be change now inside Spurs.
I would say compared to Mourinho, Klopp is doing things much better. They keep the possession and they keep on attacking. Yeah it sure is hard time for Reds without their main man in defence and their attacking not working as well but they sure are gonna find something if they keep on attacking.
