Italy global Jorginho passed home a fearless penalty in the 45th minute as Maurizio Sarri earned his first competitive win at the helm after his team went down to Manchester City in the Community Shield last weekend, while fellow debutant and the world's most expensive goalkeeper Kepa Arrizabalaga started with a clean sheet.
"I wish him good luck at Real Madrid, but now we have to concentrate on Kepa because he's our goalkeeper".
Sarri's side pushed Juventus hard for the Serie A title last term but ultimately fell short as the Bianconeri won a seventh straight league title, but Chelsea were impressed enough to appoint the 59-year-old as the successor to fellow Italian coach Antonio Conte for the 2018-19 season.
The new boss got his brand of football known as "Sarri-ball" off to a winning start at Huddersfield's Kirklees Stadium, as goals from N'Golo Kante, Jorginho, and Pedro earned three points for the West London club, but it wasn't just the action on the pitch which proved notable.
"When we arrived in Madrid to make the signing, I had his parents, his brother, his sister, his child, the mother of the child, everyone is there and I said to him that I am delighted to make a great deal for him in going to Real Madrid but also it's a family coming together". Three goals and a clean sheet. I have to adapt myself to the characteristics of this championship and of (my) players. "We moved the ball well and to have a good bench is always good".
But Chelsea again punctuated a strong spell for the hosts with a goal, Jorginho sitting debutant Ben Hamer down with a skip in his run-up for an incredibly cool spot-kick after Christopher Schindler caught Marcos Alonso at the end of a neat move from the Blues.
Fans who have grown accustomed to seeing Kante sit in front of the defence and break up play with his matchless tackling ability and knack for interceptions were surprised to see the French midfielder occupy a more attacking position for large stages of the game.
Mounie took exception to Jorginho's cheeky penalty, adding: "It was weird".
"It was a little bit weird. The ref needs to explain that to us because I don't understand why (it was not retaken)".
