Olivier Giroud scored all four goals during a comprehensive Chelsea victory over Sevilla that ensures the Blues take top spot in Champions League Group E.
The Frenchman scored early in each half with two delightful finishes after being fed by clever passes from Kai Havertz and Matteo Kovacic respectively.
He completed the treble with a flicked near-post header, then converted a penalty after he was bundled over within the box.
Already assured of qualification for the last 16, Chelsea made nine changes to the team that drew 0-0 with Tottenham within the Premier League on Sunday.
Both Havertz and Christian Pulisic made their first Blues starts since October following illness and injury, while 19-year-old midfielder Billy Gilmour came off the bench for his introduction of the season.
Sevilla, also sure of their place within the knockout stages, were without variety of first-choice players and were forced to offer a debut to goalkeeper Alfonso Pastor after Tomas Vaclik was injured within the warm-up.
There was little the 20-year-old could do about the goals and his saves ensured Chelsea’s winning margin wasn’t greater.
