Apart from swapping Akanji for Nunes I can’t see any other way of meeting the squad numbers. Kovacic‘s injury won’t make any difference whether he stays or not ,injured players have move before.Stones or Ake could go but I wouldn’t be surprised if they didn’t.
Pep wants a small squad, which can work if you don't have injury prone players. Otherwise, we haven't learned the lesson from 24/25.
1-2 players won't be registered for the CL or will be loaned out.
What makes sense for us fans may not make sense for Pep, and vice versa. Expect surprises.
