Defensive midfielder: Jorginho
Chelsea's pass master, Sarri has built his team around his Napoli protege and on current evidence, it's working to great effect. Jorginho's 853 passes is the most by a country mile, but those weren't just pointless kneading of the ball like that of Spain in their round of 16 games against Russia.
His passes are incisive, defence-splitting and picks out players in good positions when Chelsea are in the attack. It's this facet of his game that can cause the undoing of United on Saturday.
Left-midfielder: Paul Pogba
Despite the annoying public denunciation by his manager, Pogba returned as a World Cup winner and has got off to the new campaign in the same vein. He's been operating from a slightly advanced role that pretty much explains his confidence, while the Frenchman has also chipped in with two penalties, both of which came in the first two league games, to go with an assist. But his average of 3.3 shots per game shows he's become a real attacking threat these days.
Right-midfielder: N'Golo Kante
Ever quiet but evergreen, Kante has been shunted to the right side of the midfield since the arrival of Jorginho, but that's hardly impacted his game as he continues to be impressive. The Frenchman is seen getting more involved in the attacks, however, and also has a goal to back the claim.
But he remains the battering ram of Chelsea side to break opposition defences with his terrific work-rate and link-up play.
