Yes and no. Which is why I tend to treat it in terms of the 21 limit. We have always had Fodens, Palmers, Garcias, Celinas, Bobbs, Delaps, Lewises etc. on top of the 20/21. Granted, Lewis is better than most we have had in terms of the contribution he will likely have.
If we sign nobody, this will be the first time we go into a season with 19 of the 21. That's not a complaint or a concern, just an observation. It is indeed blurred by the youth, but I think it always has been, so the difference still applies imo.
I doubt Pep is unhappy with what he has regardless, otherwise things would be happening or have happened already, and that is more than good enough for me.
