Gvardiol and Akanji have been overplayed due to other players being often injured. They are the last to blame. At least they are there almost every game.
The academy players shouldn't be relied upon in such difficult moments. Anyone thinking they wouldn't be worse than Gundo or Bernardo is being foolish.
Shit seasons happen. It's normal to have injuries and to be unlucky after 4 great seasons. The most realistic chance for a big trophy this season is the club world cup when Rodri may be back. Rodri is not as brilliant on the ball as David Silva or KDB, but he is a more important player than any of the legends from the PL era.
