If I were Berta, this is what I'd do (June 16th edition):
Sell: Trossard and Zinchenko.
Buy: Kepa, Zubimendi, Sesko, Rodrygo, Eze, defensive depth (the Brazilian CB from Lille, Alexsandro, or Hato)
Rodrygo (Martinelli/Eze) -------- Havertz (Sesko) -------- Saka (Nwaneri/Eze)
--------- Rice (Eze/Merino) --------------- Odegaard (Eze/Nwaneri) ---------
------------------- Zubimendi (Partey/Rice/Merino/MLS) -------------------
MLS (Calafiori) -- Gabriel (Kiwior/Alexsandro) -- Saliba (Alexsandro/White) -- Timber (White)
------------------------- Raya (Kepa) -------------------------------
We'd have depth at every role 1:1 but also have versatile players like Eze that could get minutes at 4 different positions. I'd argue that Eze might even displace Odegaard at 8, although I doubt Arteta would bench a healthy Odegaard. Sesko would have time to adapt to the league but at the very least would be an impact sub off the bench for the first few months. My only worry would be speed across the team as Rodrygo isn't a burner but we collectively upgrade our technical ability by a good deal with Rodrygo and Eze joining, both of which would thrive in UCL knockouts where we have been craving some individual brilliance. Personally, I think this team wins a trophy next year and also think we can realistically bring in these 5-6 players. I'd be okay with other wing options in order to allow us to get Eze, as I am just a huge believer in his talent and fit in our current squad. Assuming that Nico is heading to Barca, I'd be fine with Anthony Gordon, Barcola, Gittens or even going for a development prospect like Nusa on the left if it meant that we could also bring in Eze.
