If you throw in a similar spine albeit better quality into the Liverpool side, you'll see Liverpool wipe the floor with Spurs. Why? Spurs may have that better spine at the moment, but do they have the necessary x factor that Mane, Coutinho and Firmino have?
I also disagree with the Alli better than Lallana debate. In my honest opinion, Adam Lallana is the best English attacking midfielder in the league. His performances prior to injury proved that. He produced his best return since his Southampton days.
Jurgen Klopps Liverpool will evolve, they will become stronger. Man City will become stronger when Pep signs reinforcements and signs Pep players in the spine of his team. Attacking wise, he's signed players on another level to Spurs in Gabriel Jesus and Leroy Sane. Mourinho will build a Mourinho side that will be in his own image. It isn't as of yet, and nowhere near it. Zlatan admitted as much. Spurs on the the other hand will stand still. There is very little room for improvement. This is to do with both the style of play of the manager, the clubs ambition, and their wage structure.
Anyone will be theirr mortgage will bet that Jurgen Klopp will build a team of champions long before Pochettino does.
