Depends on what for,
Robinho is our most skillful player, he has the best control, he can unlock a defence better than anyone else and he can score goals in tight games that no one else can in our team.
Bellamy has the pace, passion and fight that no one else in the team has.
I think against Chelsea for example a really tight team solid across the pitch robinho probably can be better in other games I would have Bellamy, in some games both of them and rest ade.
Overall though you have to say someone who has played 65 games for Brazil and played for real and done what robinho has done edges it over bellers.
It is a silly question though we need both and we need to have both.
