Inter Milan striker Samuel Eto'o has threatened to pull out of this summer's World Cup following criticism from Cameroon legend Roger Milla.

Eto'o made history last weekend when he completed a league, cup and Champions League treble for the second year in a row, having achieved the feat with Barcelona last season. But Milla claims the forward has "never given anything to Cameroon".

"Is it really worth going to the World Cup?" Eto'o said on Euronews. "I am going to see if my participation is important because I don't need it for my career."
