For what must be the first, and may well be the last, time ever Jamie Carragher will be supporting Manchester United when they take on Man City in the Manchester Derby on Wednesday night.
Carragher is a Liverpool legend, a Scouser born and bred and was a main character in the fierce rivalry between United and Liverpool for well over a decade during his 17-year stint at the club.
There's never been much love lost between Carragher and United but he has revealed he will be supporting his old foe on Wednesday night by posting a brilliant photo on Instagram.
The photo is of Carragher laughing while wearing a United shirt accompanied with the caption "for one night only!".
It's no surprise that Carragher is hoping for a United win as it would hand his beloved Liverpool a massive advantage in the Premier League title race.

Liverpool currently hold a two point advantage over Man City at the top of the table but the meeting with United is City's game in hand.
Should the Blues claim all three points then they will be ahead of Liverpool with both teams playing the same amount of games, with three more to go.
If United don't lose, however, they could hand their fiercest rivals their first ever Premier League crown.
