​Arsene Wenger has thrown out a warning to Real Madrid forward Cristiano Ronaldo, saying that obsessing over being the single best player in the world over Lionel Messi could make him selfish.

The Portuguese star recently talked about how important individual awards were to him, saying that it was 'hard to watch' when his Argentine rival was on his own Ballon d'Or winning spree. 

However, ​Wenger told reporters: "He is the best player in the world - with Messi. Messi has a little advantage on assists. But I would go for nobody because it is not my problem at the moment. I’ve seen careers being destroyed because players are too obsessed with individual rewards.

“I can tell you that maybe another day but it encourages selfishness. And it encourages people inside the game to go more for their own gain when others are in a better position. You can be No.1 in the world in March and no.250 in May. Sport is always moving."

Ronaldo will face his great rival Messi's Barcelona team straight after the international break, but the Argentine won't be there to square off against him as he continues to recover from injury. 

Speaking this week, Ronaldo said: “If you look back over my past eight years, I’ve always been at the peak; and that is difficult. Name me someone else who has done it? After that, being No.1 or No.2 is a matter of small details, such as if you win trophies or not. 

“Perhaps for you, Messi is the best; in my head, I am the best – and everyone should think that about ourselves. That is why I have been able to achieve so much in my career. It was hard for me to watch Messi picking up several Ballon d’Ors. I’d be thinking, ‘Why should I go to the gala?’”
