One memorable tackle on Lionel Messi was a highlight of the young centre-half's night.
The challenge led to an outburst of 'there's only one Gary Cahill' from the home support - the first time that has happened since his move to Stamford Bridge.
"I could hear that being sung and it was obviously tremendous and a proud moment for me," Cahill said.
"You can't get the ball off him (Messi) can you?! Even if you have four or five surrounding him, but I managed to get the tackle in."
