Trent Alexander-Arnold taunted Manchester United fans by reminding the fans waiting in the Old Trafford car park of the score after he was booed while heading to the Liverpool bus.
The 25-year-old right-back played a crucial part in Liverpool's 3-0 defeat to Manchester United at Old Trafford but saw his early goal from Luis Diaz's cross ruled out for an offside call to cancel his Steven Gerrard-inspired celebration.
However, a video shared on social media captured the moment the right-back was booed and jeered by some United supporters who were waiting outside Old Trafford. Arnold in the video responded by holding three fingers, and his teammate Mohammed Salah ushered him along with a smiling gesture.
