Pep hasn't been as dogmatic in his attempts to play out of the back (like he did in his early years in BM) , and the last couple of games it feels like he's had an upper hand on Klopp. Learning when the pressing trap is tight, playing balls past the first and second press into open spaces and then having 2-3 runners from behind. Pep has really turned the tables, and has beaten Klopp at his own game.
Sane and Sterling have been lethal on the break.
I think City will be marginally weaker without Sane, and with the injuries that City has I think/hope that this game will be more even. Liverpool dodged a bullet at Anfield, last year.
