Newcastle fans figure out who's responsible for iconic photo on Sunderland pitch

The Magpies assistant is well-known for his touchline antics and was at his s***housing best for the Tyne-Wear derby.

Newcastle knocked neighbours Sunderland out of the FA Cup at the third round stage, taking an easy 3-0 win away at the Stadium of Light.

The Alexander Isak-inspired victory came as the two sides faced-off for the first time since 2016, reginiting one of English football's greatest local rivalries.

Pre-match preparations were focused on a bar in the away end embarrassingly draped in Magpies gear, and they managed to get another one up on their rivals after the game.

Newcastle have a tradition of group photos in the changing room after victories, with the club often posting shots on social media.

But after a win on enemy territory, they decided to take the tradition out onto the pitch, much to the annoyance of the home fans.

Boos ran out from the departing home fans, while the travelling 6,000 Geordies were absolutely loving it.

Now they know who they have to thank for the idea, with a clip going viral of Tindall orchestrating the on-pitch jibe.

Eddie Howe's assistant was captured calling over the club cameraman while the team were applauding their fans, pointing to the pitch, and signalling a camera with his hands.
