Real Madrid goalkeeper Thibaut Courtois received a hostile reception from Chelsea fans on his return to Stamford Bridge.
The Belgium goalkeeper is yet to be forgiven by Chelsea fans for his decision to leave the club for Real Madrid in the summer of 2018.
Courtois played four full seasons at Chelsea after spending three years on loan at Atletico Madrid.
On his return to Stamford Bridge on Tuesday night, Courtois was booed and insulted by the home crowd over the course of the 90 minutes.
However, his response at the end of the match has subsequently gone viral.
After Real Madrid beat Chelsea 2-0 at Stamford Bridge, Courtois reacted to insults from Chelsea fans by kissing the badge on his Real Madrid jersey.
