If Saliba comes back and Nketiah signs a new contract then yes, otherwise we’ll need a new 3rd choice CB and another striker to compete with Jesus. Unless Gakpo can play upfront.
I assume it’d be more or less that.
I guess the key thing for me is that the technical level will go up again and we’re filling the squad with hungry and relatively young players. Sets up the club quite well in the future, with or without Arteta/Edu.
I’d like to see a marquee player like Sterling or Osimhen come here but that seems unlikely, especially if we don’t get CL football.
So the players you’ve listed are probably a pretty good prediction of what is going to happen and should be enough to at least challenge for a top four place.
