As you guys referring to next season, I see many difficulties for Tottenham to replicate what they have done this season:
Good signs for them:
+ Chelsea and Liverpool will have to compete in Europe (either CL or EP)
+ They are a rising team. This would be probably the best sign for them. This season is better than last season. So next season, there probably will be another improvement.
Bad signs for them:
- Less home ground effects. This would probably the biggest problem for them. They stand 1st on home while 4-5 on away game tables respectively. A move to Wembley will reduce that home ground advantage (just see West Ham and Spurs records at Wembley in Europe this season - both are terrible).
- United and City will improve a lot. Pep and Jose are not kinds of managers who are not able to recognize their problems and transform their squads. Especially, Jose often wins the league in his second year at his clubs. Both will have a massive amount of money to spend also.
- Chelsea will spend big too. Just because there is so much money in our pocket (kidding
but that's true)
- Not sure if Spurs will spend big, despite of some lacking in depth in the squad. History say no, unless they are going to sell 1-2 stars which is unlikely this summer.
I don't mention about Arsenal because there are so many possibilities can happen to them this summer, either in a good way or bad way for them.
Anyway, Spurs is having a very good season. The league is till not over also.
