Txiki isn't sat in the room with Pep and pulling the wool over his eyes by convincing him that Nunes is the second coming of Rodri. They all have to be a level of responsibility.
Doku was a signing for the future and he's shown a lot of flashes that he can give us a lot I think, expecting him to replace Mahrez is ridiculous and that is a fan expectation not from the club.
Kovacic is what he is, pretty reliable and dependable squad midfielder. He starts for every club outside the top 4. Again, fan expectation seems to be that he should be as good as Rodri.
Did Barca have a choice with Gundogan?
Pep needs to shoulder blame, sometimes his own genius and arrogance is to the detriment of the team.
