Thats a very fair comment but as Pep as stated on many occasions "if a player doesn't want to be here they can go".Football and fortunes change quickly as we have seen with the return to form of John Stones and the emergence of Dias, but can change for the worse just as quickly.
IF we lose Laporte, and either Dias or Stones have any sort of issues, the drop off in ability to Ake in my opinion is huge and could be the difference to retaining the title.
I agree we would be short of cover if he goes but surely the club would of discussed this and have plans in place for this happening, i could be wrong though as i'm just a mere fan
