Football can be incredibly divisive. It's tribal nature often puts the 'us vs you' narrative at the forefront of a match day, but every now and again something happens to bring the fans together under the same roof.When English sides travel in Europe, their fans aren't afraid of making themselves known. Usually it's by commandeering the town squad and setting up at a bar for a bit of a sing-song before carrying on inside the stadium.On Thursday night when Manchester United travelled to Celta Vigo for the first leg of their Europa League semi-final, the fans who'd made the journey weren't given much to cheer in the first half.A number of chances fell United's way with Marcus Rashford, Henrikh Mkhitaryan and Jesse Lingard all going close, but for a while it looked as though it was going to be one of those nights where things weren't going to go their way.Of course, it all came up roses in the second half thanks to a superb free kick from Marcus Rashford, who gave the Red Devils a huge boost going into the second leg by handing them a 1-0 lead in the tie.But before then, the people behind the scenes at Celta did something brilliant to get the crowd going, only the reaction was far better than they could have imagined.As the two teams re-emerged for the second half, the theme from 80s TV show The A-Team was blasted out over the speakers, much to the delight of both sets of fans.Everyone rejoiced in humming along to the famous tune, and even the BT Sports commentators couldn't believe what they were hearing.

Brilliant. It proved an inspired move and it would be no surprise to hear Premier League clubs adopting it in the near future.

Sadly for Celta, though, it didn't have the desired effect for their players and they were unable to seriously test the United defence.

Fans watching at home on social media also joined in on the excitement, posting their reactions to Twitter.

Just brilliant. More of this!
