Frank Lampard likes his superstitions, so he will be interested to know that the last time Chelsea won four consecutive Champions League matches was when he was part of the 2012 team that went on to win the trophy.
Chelsea's fourth successive victory secured top spot in Group E with a game to spare and came courtesy of a sensational four-goal salvo from the evergreen Olivier Giroud, who has certainly put himself in a strong position to start the Premier League game against Leeds United this weekend.
Lampard made nine changes from the team that had drawn against Tottenham Hotspur, with only goalkeeper Edouard Mendy and midfielder Mateo Kovacic keeping their places.
And it was two of the players who came in, Kai Havertz and Giroud - on his way to netting a perfect hat-trick and then adding a fourth from the penalty spot - who combined to put Chelsea ahead after 10 minutes.
Havertz, making his first start since recovering from coronavirus, had already forced Sevilla's rookie goalkeeper Alfonso Pastor into a save at his near post, before setting up Giroud to score. The Germany international glided forwards with the ball and slipped a lovely pass through for Giroud, who expertly shifted the ball on to his left foot and curled it into the net.
Lampard had claimed 34-year-old Giroud was getting better with age, after he had headed the winner against Rennes a week earlier, and his finish in Spain suggested his head coach might have a point.
Giroud had gone off clutching his ankle at the end of the first half and then was furious immediately after the restart when he was not awarded a free-kick after going down under a challenge from Gudelj, who could have earned a second yellow card.
But it was not long before Giroud was smiling again, as he netted his and Chelsea's second goal in the 54th minute with another superb finish. This time it was Kovacic, who received a pass from Jorginho, with the assist.
Lampard made three changes with just over 20 minutes and it showed the strength in depth Chelsea have that he was able to send on N'Golo Kante, who produced the cross from which Giroud produced a trademark header to complete his perfect treble, Hakim Ziyech and Mason Mount with a two-goal cushion.
Giroud still had time to win and score the penalty that made it four for him and four for Chelsea.
