Its a pre-season game so its always difficult to analyse it fully, but I think its pretty obvious that this team still carries the same issues that have plagued us over the past 2 seasons and Pep has a big job on his hands.
Granted we've added a lot of depth to the wide positions and we are fine in the number 10 position - Glaring weaknesses are STILL left back, central defence without Vinny and midfield. Back up to Aguero is an issue but not an alarming one as Kalechi always seems to produce when played.
I would argue that we are heavily reliant on both Gundogan staying fit and Yaya coming back a lot leaner - as Fernandinho is literally the only central midfielder we could truly rely on last season. Again, any injury to Sergio (which sadly happens at least once every season) and were also going to be short up top.
Stones is a must.
