I don't know why that would be unrealistic. It's not like they were Xavi, Iniesta, Modrić etc. But they were still excellent and the best we had.
SMS, Pogba, Partey, Kroos, Luis Alberto, Fabian Ruiz, Thiago, Kante, Havertz, Aouar... Probably missing some other guys too.
Thiago is leaving Bayern, they want 30-40m. That's a bargain even though I don't particularly like him. Partey has a 50m release clause. Aulas wants 50m for Aouar. It's rumored Chelsea wouldn't mind selling Kante for 60-70m and rejuvenating their team.
Aouar-Thiago-Partey is right there for less than 150m all together. It's baffling we're not all over that.
Add Bentancur, Arthur and Locatelli and we may have something again.
