I think last season was the last hurrah of the original team he'd assembled at Liverpool. Mane (left), Salah (declining), VVD (declining), Henderson (declining) are either not there or declined.
The other issue, is the likes of Fabinho and TAA (who aren't even old) have seemingly lost form for whatever reason. That's not guaranteed to return unless they reinvent or take up a new challenge elsewhere.
The question is whether the V2 players (Gakpo, Diaz, Nunez, Jota, Konate) were good enough to replace the originals.
