Pitch invader who jumped at Erling Haaland turns out to be former WBO world champion Terry Flanagan

While Erling Haaland was not really in the mood to celebrate his goal against Sheffield United after wasting many chances, one supporter was.

A guy from the Man City away section leapt at Haaland's back, much to the amusement of the Norwegian and fellow City footballers.

As it turned out, it wasn't just an ordinary fella but Terry Flanagan, a retired British fighter who held the WBO lightweight title between 2015 and 2017.

Flagan is a huge Man City fan and once even showed off his belt to the Etihad crowd, something that is still unlikely to save him from a lengthy stadium ban.
