Chelsea boss Jose Mourinho has paid tribute to Barcelona star Lionel Messi.
Mourinho insists Messi doesn't need to win the World Cup to be considered one of the game's "greats".
"He [Messi] is great, he is great. I don't think he needs to win with Argentina to be great. Ronaldo is great; I don't think he needs to be world champion with Portugal to be great. But - and there is always a but - Maradona did it, and Zidane did it, and Ronaldo Nazário and Rivaldo did it. Many of the big guys did it, so everybody is waiting for them to do it."
