I feel this is at least significantly in part because our three technical offensive players have all either barely played this season (and when played, clearly been playing through injury) - Saka, Odegaard - or been settling in (Eze).Our midfield has been the single biggest issue, a chronic lack of creativity and as you say, getting overpowered and overrun far too easily.
It’s galling to see teams pass through us so easily and for us to get through a team's midfield we have to fight tooth and nail to make progress.
We’re left with athletic runners who can’t do anything without the technical guile.
Front four needs to be at least two technical players, ideally three. We’ve regularly played with one or two and most of those have been playing at 60% fitness.
City have three.
PSG have three.
