The hosts were playing their first home game since George Baldock died at the age of 31 on 9 October.
Before kick-off, Panathinaikos players trained in shirts with Baldock’s squad number of 32 on them, while Chelsea players also held up a shirt bearing his name and number. Both sets of fans also held up placards with 32 on them.
David Bowie’s Starman played through the PA system, in reference to the former Sheffield United player’s nickname.
Visiting boss Enzo Maresca made 11 changes for the game and it took a while for Chelsea to settle, but they broke through with a well-worked move on the counter, Felix playing a one-two with Mykhailo Mudryk before sweeping in from close range.
Mudryk made it 2-0 soon after the break when he headed in Pedro Neto’s cross for his first goal of the season, and the Ukraine forward was the provider again for Felix to get his second, with his strike taking a deflection on its way into the net.
Christopher Nkunku wrapped up the comfortable win for Chelsea, firing home a confident penalty after Daniel Mancini’s foul.
Former Manchester United midfielder Facundo Pellistri swept in a consolation for the hosts, but it was ultimately a comfortable win for Chelsea, who maintain their 100% record in the league phase.
