#3 Ole Gunnar Solskjaer: Liverpool
Yep, Manchester United legend Ole Gunnar Solskjaer actually grew up supporting North-West derby rivals Liverpool when he was a young kid growing up in Norway.
But you can't blame him for supporting the Reds back then. It was in the '70s and '80s when the Anfield side reigned supreme in England.
"You know when you are back home and you watch games on television and you tend to support the team that is winning. So in the '80s Liverpool were winning.
"Kenny Dalglish, he was the best player I thought, then Marco van Basten and Zico. But in England Liverpool won, so you get caught up in the moment."
Solskjaer would then prove himself with Norwegian club Molde before sealing a move to Old Trafford after United failed to land Alan Shearer.
The 'Baby-faced Assasin' would then score 18 times in his first season to help the Red Devils seal the 1996/97 league title, pipping Newcastle to the finish line.
Of course, he would then go on to become famous for what was arguably United's biggest goal in history - the last-minute winner in the 1999 Champions League final to seal a famous treble.
