Still, teething problems were to be expected given the Italian manager's arrival halfway through preseason, and Chelsea can take heart from the win, earned with their best attacking player, Eden Hazard, sitting on the bench for 75 minutes.
Sarri acknowledged that his team struggled against Huddersfield in the first half on Saturday because they lacked the tactical grounding is his way of playing to adapt to Huddersfield's back three - a system they hadn't yet faced in pre-season.
"I think he (Kepa) did well", Rudiger said.
"Everybody, I could see tears in their eyes, and it delighted me very much because I had the feeling to do something not only for a deal, not only for a player, not only for my client, but also for a family, which is great". In the first line, we defended not like we wanted to defend.
"I am really very happy because in the first part of the season I think it is not easy for us to gain points", Sarri said. Maurizio Sarri's side bossed possession from the outset in West Yorkshire, where it took 20 minutes for Alex Pritchard to muster a shot on target - an attempt that was straight down the barrel and comfortably stopped.
'Maybe for Napoli in the previous year it wouldn't have been a problem but for Chelsea, with some of the players only having had three days of training, it was a problem'.
The Blues were forced to move for a replacement keeper late in the transfer window as Thibaut Courtois pushed for a move to Real Madrid. "They had five chances and scored three goals", Wagner told reporters.
The Blues' new star in the midfield is Jorginho, who came over to Chelsea with Sarri from Napoli. "If you see the result you think it was a very easy match but in the first half, it was very hard against physical opponents", He told the BBC.
"He jumped before the penalty and Ben (Hamer) had already dived so I don't know why the ref didn't make him retake the penalty. The ref needs to explain that to us because I don't understand why (it was not retaken)".
