'We are massive' - funny BT Sport tribute to Leeds United spotted during Manchester City v Wolves
Leeds United fans are an eagle-eyed bunch - so much so that nothing gets past them even when other teams are playing.
The Whites are enjoying a midweek free of match action in the Premier League but that didn't stop Leeds turning up at the Etihad on Tuesday evening.
Manchester City hosted Wolves in the top flight across the Pennines and for those watching on they will have noticed something peculiar.
During the first half of the contest the Elland Road club's famous anthem 'Marching On Together' appeared as part of BT Sport's fake crowd noise sound effects.
A mistake, clearly, but a funny one nonetheless - and supporters were quick to pick up and poke fun at the incident.
On the pitch Pep Guardiola's men ran out 4-1 winners as they made it 21 wins in a row but off it Leeds fans made sure the mistake didn't go unnoticed.
Here's what supporters had to say in today's social media talking point:
@mattsamstring Just heard Marching On Together as part of the fake crowd noise during the Man City v Wolves game. BT Sport sound guy is obviously a Leeds fan
