Graham Potter saw his side play out a 1-1 draw with RB Salzburg in his first game in charge of the club.
Chelsea dominated the game but couldn’t get all three points despite taking the lead through Raheem Sterling early in the second-half.
Potter went for a weird makeshift backline that had Cesar Azpilicueta and a 37-year-old Thiago Silva.
Aston Villa legend Gabby Agbonlahor was critical of the system, as he believes Wesley Fofana and Kalidou Koulibaly should have started.
Agbonlahor said on talkSPORT: “He (Potter) needs to pick his best two centre-backs and just give them game time.
“That’s got to be Koulibaly and Fofana, the money they’ve been bought in for.”
