Our last six" big" signings, unless I'm forgetting someone:
22/23
Gakpo, Nunez
21/22
Konate, Diaz
20/21
Jota, Thiago
I'd say that's more hit than miss. Unless you mean Salah, Mane, Van Dijk, Alisson wise "high quality", then indeed our signings have been more in line with what was expected rather than they took one or two steps forward or exceeded expectations, yeah - agreed.
I think Mac Allister will have a role similar to Wijnaldum - if he turns out to be a player in his mould, I think I'd be happy enough with that. Our midfield desperately needs reinforcements anyway so at the very least he'll provide depth, and think he'll be getting a lot of games.
