Jorginho made his Chelsea debut one to remember by scoring a penalty just before half-time of a 3-0 victory over Huddersfield Town at the John Smith's Stadium on Saturday.
The midfielder, who joined manager Maurizio Sarri in moving from Napoli in July, scored in the 45th minute to help usher in the new era at Chelsea.
N'Golo Kante opened the scoring in the 20th minute by volleying in a cross from Willian, and after Marcos Alonso was taken down in the penalty area by Christopher Schindler, Jorginho stepped up and coolly netted with goalkeeper Ben Hamer frozen.
Pedro made it three in the 80th minute by chipping in over Hamer after he was fed by Eden Hazard, who came on as a substitute.
Chelsea keeper Kepa Arrizabalaga, signed on Thursday in a record transfer ahead of the deadline, was rarely challenged and did not make his first save until the 20th minute.

Vertonghen opened scoring in the eighth minute from a header that the Goal Decision System showing the ball crossed the goal line by 9mm.
Newcastle answered in the 11th minute when Joselu headed a cross from Matt Ritchie past Hugo Lloris, but Serge Aurier sent a long cross into the box that Alli tucked in after breaking past DeAndre Yedlin seven minutes later.
U.S. defender Yedlin limped out of the game with a knee injury in the final minutes, and Newcastle, down to 10 men, could not find an equaliser.
Richarlison scored twice in his first Premier League appearance for 10-man Everton, but a late goal from Raul Jimenez helped Wolverhampton Wanderers salvage a 2-2 draw at the Molineux Stadium.
After scoring when Michael Keane's free kick into the mixer fell to his right foot in the 17th minute, Richarlison scored his second in the 67th minute, using Connor Coady as a screen to beat Rui Patricio.
But with Phil Jagielka sent off in the 40th minute for a hard tackle, Ruben Neves scored from the resulting free kick, and Raul Jimenez slipped past Keane in the 80th minute to finish from a header for the equaliser.
Crystal Palace spoiled the return of London rivals Fulham to the Premier League with a 2-0 victory at Craven Cottage.

Wilfried Zaha then added another in the 79th minute after he was played in by Aaron Wan-Bissaka and scored right-footed around charging goalkeeper Fabri.
Roberto Pereyra bagged his first top-flight brace as Watford claimed three points in their opener with a 2-0 victory against Brighton & Hove Albion.
