Pedro struck twice and Michy Batshuayi and Willian were also on target as Chelsea secured a routine 4-1 win over Peterborough United in the FA Cup third round, despite John Terry's second-half red card.
Antonio Conte rotated his squad for his first taste of FA Cup action, with captain Terry restored to the starting line-up, Kurt Zouma making his first senior start in 11 months and Batshuayi deputising for Diego Costa.
Chelsea went in front after 17 minutes of Sunday's tie at Stamford Bridge despite the changes, though, with Pedro thumping home after Luke McGee had saved Nathaniel Chalobah's powerful drive.
