Eze is a good signing but not at the expense of a potential game changing LW or ST (whoever that might be).
Ideally we get Eze, Rodrygo and Gyokores/Sesko. This would mean our attacking options would be:
DM's: Zubi, Norgaard (Rice, Merino and MLS all capable of playing here too)
8: Rice, Merino (Eze, Nwaneri, MLS all options as well)
AM: Odegaard, Eze (Nwaneri as cover, maybe even Rodrygo)
Wingers: Saka (RW), Rodrygo (RW/LW), Martinelli (RW/LW), Eze (LW), Nwaneri (RW)
ST: Havertz, Gyokores, Sesko
Trossard would need to be sold/loaned out, and I would consider loaning Nwaneri out to a Bundesliga/La Liga/Serie A/Ligue 1 side.
I think the above is the minimum we need to compete next season. Anything short of that and we WILL finish 3rd at best.
