1.) Manchester United(Pogba signing will make me feel more confident about this prediction, alongside how we line up. Dependent on these two factors, it can be the difference between first and battling for a champion league place.)
2.) Manchester City
3.) Arsenal
4.) Chelsea (A surprise package, because they will perhaps have the best defense in the league. With no European football, they could pose a good title challenge.)
5.) Liverpool(might be another surprise candidate for this season if Sturidge and Coutinho stays fit and continue upon their last season performance. Klopp enthusiasm will successfully rub onto their players and they will reap the benefit of that. )
6.) Spurs
Too early to tell, because there is still some transfer activity that will take place. I could see United easily winning the league or battling for champion league spot dependent on how we are being manage. With that said, I believe all the teams listed above is stronger than United, but with Mourinho in charge perhaps he will give us that secret formula to success that will give us the competitive edge.
Update:
1.) United
2.) Arsenal(if add new player, else fourth)
3.) City
4.) Liverpool
5.) Spurs
6.) Chelsea
