#2 Cristiano Ronaldo
It's the dream for a lot of football fans to see Cristiano Ronaldo and Lionel Messi play in the same team. That dream was almost a reality in 2009 but the Portuguese international rejected Barcelona as he wanted to join Real Madrid.
Sir Alex Ferguson was not happy with Madrid luring his best player to Bernabeu so he offered Ronaldo to Barcelona. The Catalan side were keen on securing a deal but were unable to convince Ronaldo to sign for them.
In March 2014, Former Real President, Roman Calderon confirmed that Ronaldo indeed rejected Barcelona: “In the few weeks, he tried to avoid him going to Real Madrid, offering him to Barcelona. Barcelona were very happy but at that moment but it was very crucial as Ronaldo said: I'm not going to any other club but Real Madrid.”
