The Manchester City fan who celebrated with Erling Haaland after his goal has been revealed as a former world champion boxer.

Terry Flanagan, a retired British professional boxer who held the WBO lightweight title from 2015 to 2017, joined in the City celebrations with Haaland on the pitch.

The 34-year-old had an impressive record in the boxing ring, with just two losses in 38 fights and 14 knockouts during his career.

Flanagan was present to witness his team’s 2-1 victory over Sheffield United at Bramall Lane on Sunday afternoon. The match saw Haaland miss a penalty as Man City struggled to break down a resilient Blades defense.

However, the Norwegian international eventually found the back of the net by heading home a cross from Jack Grealish. In an enthusiastic moment, Flanagan made his way from the stands onto the pitch and was observed jumping on Haaland’s back while participating in the City celebrations.

Flanagan was also seen affectionately kissing Haaland’s neck, leaving Bernardo Silva visibly surprised by the unusual display of affection. Security personnel quickly intervened, removing Flanagan from the scene and escorting him out of the stadium.

Despite Jayden Bogle equalizing for Sheffield United in the 85th minute, it appeared that the Blades had secured a point. However, Man City midfielder Rodri had different plans, scoring a goal to ensure his team left Yorkshire with all three points.

Pep Guardiola’s side will return to action when they face Fulham in the Premier League at the Etihad Stadium on Saturday.
