Thomas Tuchel fielded two different XIs in each half as he sought to give his entire squad some minutes after the summer break.
Ross Barkley, Danny Drinkwater, Callum Hudson-Odoi, Trevoh Chalobah, Malang Sarr and Davide Zappacosta were among those to start with Hakim Ziyech coming off the bench to score a hat-trick in a 6-1 win behind closed doors.
The Blues fell behind earlier on with Siriki Dembele opening the scoring from the penalty spot.
Tammy Abraham levelled however before Christian Pulisic scored a spot-kick of his own to ensure his side went into half-time in the lead.
Ruben Loftus-Cheek, Armando Broja, Conor Gallagher, Baba Rahman and Ziyech were among those on for the second-half with the Moroccan on the score sheet after firing home off the underside of the cross bar.
The former Ajax star grabbed another two with 19-year-old Broja also on target.
