Alan Pardew celebrated Crystal Palace's 1-0 victory over Southampton by joining the club's fans in the pub.
Yohan Cabaye scored the only goal of the game, after which the manager joined the Holmesdale Fanatics supporters group.
Assistant manager Keith Millen was also present on the 10th anniversary of the foundation of the fans group.
The 54-year-old steered Palace to safety after joining the club in January and has led the team to sixth in the Premier League table this season.
