When did we have no injuries last season mate? When did carlo have a full squad?
Please point out all those games when he had his full first 11 available and zero injuries.
He didn't, but that's not what people are saying - the difference is the sustained issues and just how many key players have been missing or playing half-fit.
You can easily point to Ancelotti playing four centre halves with Holgate in midfield against Brighton, but that was the odd game - it wasn't like five on the spin, and he pretty much always had a genuinely brilliant DCL available (except actually that game!)
This was the bench for that Brighton game and it may well just be the worst ever selected for a top flight game.
So yeah, the squad depth problem isn't new - but Benitez has had sustained problems with injuries.
