The stat I saw says Arsenal have the easiest one actually.
They did really well to get Jorginho, they had nothing at DM when Partey is out, and now they have a good passer to help them dominate games, even if he's not ideal defensively, though they can have Xhaka help him out a bit more and Zinchenko gives him a partner most of the time anyways. Reminds me that I wouldn't be surprised if some summer Gabriel gets sold for them to bring in a faster LCB to cover all the space behind and wide of Zinchenko.
They can even go with Partey and Jorginho together and have Zinchenko in a more attacking role (or Tierney on the touchline playing wide and Trossard in the half-space to help Nketiah with the goal-scoring load) as a plan B, which they didn't have before.
City I have no idea. Bernardo Silva at LB suggest Guardiola is going through one of his manic periods, but he's won titles before in that state, and against better opposition. I do think it's a good sign for them that he's tweaking things tactically to try to get Haaland integrated into the team rather than just seeing him struggle to get a touch in tough games and then score 4 goals against Bournemouth over and over again.
I think their back-up is less than ours:
- Tomiyasu is not having a great season
- Kiwior has just signed and is somewhat unknown in the PL.
- Tierney is not having a great season and doesn’t play a lot because of Zinchenko
- Smith Rowe is always injured
- Elneny is not good and injured
- Vieira has almost no impact on games and Arteta doesn’t play him a lot
- Nelson has been injured a lot and is not the player he looked when he was young
- Trossard not as good yet as he was at Brighton.
And they have problems with the first team:
- Jesus has been injured since the wc, they really missed him but how good will he come back
- Partey injured again and has always multiple injury spells in the season
- Xhaka is just Xhaka doing Xhaka things
- Odegaard not as good as the first part of the season where he was the best midfielder in the league
- Martinelli not as good as the first part of the season since the wc
So a lot of pressure for their star players Saliba, Saka and Zinchenko to perform to keep them in the title race.
Arteta doesn’t trust his subs and lets the first team play to much. Big chance they will bottle it. But I think City will grab it then.
