Chelsea - The clear stand outs with Havertz, Werner, Ziyech, Chilwell. They still have defensive issues with young defenders.
Liverpool - Thiago is their big signing and should strengthen their weakest area, ie creative midfield play. Jota is more about squad depth and options off the bench
City - Allot depends on how good Dias and/or turns out to be. They’ve gone for him over first choice Upamenco. I personally have no idea good these defenders. I do think their midfield needed strengthening.
United - The poorest imo. I could be proven wrong but Cavani coming to the PL as a 33yo just sounds all wrong. 35m on Van de Beek who isn’t a starter yet. They’ve also let arguably their best defender leave
Everton - transformed their midfield with James, Doucoure and Allan. Legit contenders for top 4 I think
Spurs - They’ve made Le Celso permenant and signed 2 fullbacks, which were needed.
Arsenal - Willian, Gabriel and Partey. 2 very weak areas of our spine strengthened, immensely
Leicester - no idea who there new players are tbh
So in terms of ranking transfer windows I’d go:
Chelsea
Arsenal
Everton
City
Spurs
Leicester/United
In terms of predictions for the league, I’ll go with
Liverpool
City
Arsenal
Chelsea
Spurs
Everton
Leicester
United
Maybe overly optimistic but I do think Arteta is making us very hard to beat, with 9 out 12 points so far and Partey should only re-inforce that. We now have a very strong spine. United look in freefall and even City may do worse than last season having lost Silva and Kompany in consequtive seasons with Fernandinho past his best and Rodrigo not being a good enough replacement. Chelsea I think will score plenty but concede allot. Mourinho will make Spurs hard to beat and they clearly still have a quality attack.
