At first blush, it's our signings. New goalie - Ederson Two new backs, and backup - Walker, Mendy, Danilo Another quality attacking midfielder/winger - B. Silva ========== Yet... Mendy is injured. Danilo doesn't play that often. B. Silva doesn't play that often and has not adapted to the P/L yet. =========== So why are we so much better? It can't be just down to new signings as 3/5 of them don't start regularly. I think it's down to a combination of factors. 1) Delph has filled in at LB far better than could be expected, a major upgrade over Clichy/Kolarov (Kolo better going forward but cannot press as Pep would like and due to lack of pace is often a liability on defense); 2) Ederson is so much better than an out-of-form Bravo offering excellent shot stopping skills, better distribution and confidence/command at the back; 3) Improvement of players under Pep - Stones and Sterling are vastly improved this year; 4) System buy-in - our players now buy into Pep's system more than they did last year, pressing much better than last year (Sane and Aguero in particular are now pressing much more aggressively); 5) Our squad rotation is much better - gone are Fernando, Navas, Nolito, Clichy, Zabbaleta and Kolarov; in their place are Gundogan, B. Silva, Danilo. It seems to me that our rotation isn't as deep but it's of far higher quality and consists of players that much better fit Pep's system. What do you think?
