N'Golo Kante opened the scoring after neat work from Pedro and the World Cup victor may score more goals this season as Jorginho's role gives him license to drive forward for the Blues. "The first half was hard".
However, once Jorginho had doubled Chelsea's advantage from the spot shortly before the interval, Town lost their way and could have few complaints at the score come the final whistle.
"If you want to get something out of these games, you have to be at your very best", said Wagner.
He was also involved in the move to win the penalty, as Pedro started the attack, allowing Jorginho to feed it into Ross Barkley with a perfectly-weighted pass and the England global flicked it into Marcos Alonso's path to earn the penalty.
The Blues were the sole aggressors in the second half and, after Hamer parried a header from Antonio Rudiger behind, Alonso sent an acrobatic effort against the crossbar in the 58th minute. "I have to respect the characteristics of the players, I have to adapt myself to the characteristics of the championship and of the players, so now I am studying my players".
"I am really very happy because in the first part of the season, I think that for us, it is not easy to gain points", Sarri said.
"We are not a physical team and I think the best of the game is the capacity to suffer for 15 minutes". He could have won more trophies.
Julen Lopetegui's side are in need of more top players who can help them retain the Champions League title and win more silverware, after the departure of Cristiano Ronaldo to Juventus.
"This was a goal that was easily avoidable because we have spoken about this situation the whole week, how we like to defend, and we have seen we have to be switched on".
When Sarri's Napoli team played RB Leipzig in a European tie, the German club set up a specially designed smoking room for him, though this won't be possible during his tenure at Chelsea. "We have to improve in moving the ball faster, I think".
Watford's Argentine Roberto Pereyra scored twice - the first a superb volley - against Australian goalkeeper Matt Ryan in a 2-0 victory over Brighton and Hove Albion.
