#1 Cristiano Ronaldo
Another transfer which greatly impacted the football world was when Ronaldo was sold to Real Madrid for a world record fee at that time. £80m seemed like a lot of money then but it is fair to say Real Madrid ended up getting the better deal.
Sir Alex Ferguson paid £12m in 2003 to Sporting Lisbon to acquire the services of Cristiano Ronaldo. This transfer would change the footballing world forever.
Ronaldo has gone on to become one of the best strikers in the world and has won 4 Champions Leagues with Real Madrid along with 4 World Footballer of the Year awards.
Manchester United have won trophies without Ronaldo but it has not been the same. They are still struggling to find a player who is worthy of wearing the number seven shirt which was famously worn by Ronaldo.
