Liam Rosenior's tactical gamble backfired spectacularly in the first half, but a second-half revival led by Cole Palmer's cameo secured Chelsea's place in the Champions League last 16 with a 3-2 win over Napoli in Naples.
Napoli, needing a win to avoid elimination, took an early lead through Antonio Vergara's solo effort after Enzo Fernández had put Chelsea ahead from the penalty spot. Rasmus Højlund then put the hosts 2-1 up before half-time, leaving Chelsea in disarray.
Rosenior's decision to start with only one recognised centre-back backfired as Napoli exploited the space behind Chelsea's wing-backs. The manager admitted his error by substituting Malo Gusto for Trevoh Chalobah at half-time and introducing Palmer, who had been kept in reserve due to injury concerns.
Palmer's presence transformed Chelsea's attack. He set up João Pedro for a stunning equaliser from 25 yards, then slid a perfect pass for the Brazilian to score his second of the night and seal the win. Napoli's elimination continues Antonio Conte's poor European record.
The victory means Chelsea finish the league phase in sixth place, while Napoli face an early exit from the competition. Palmer's performance, despite not being fully fit, underlined why Chelsea have rejected any suggestions of selling their star player.
