I think Pep has some problems this season. The arrival of Grealish, great player that he is, has added another attacking midfielder to an already overloaded area of the squad and Rodri's injury has exposed the need for a quality DM. Sterling or Torres at CF are not convincing and take up a place in the starting line up that could be occupied by one of our quality midfielders, so it's only a matter of time before Pep returns to a false nine. Mahrez has been ousted from the starting line up to accomodate Jesus, and he was one of our top performers last season. Pep seems a bit grumpy, not sure why, but I'm guessing he's realised that his squad is lop sided and he's lacking depth in certain key areas. This wasn't addressed during the transfer window, so we may be in for a relatively unsuccessful season.
