Rios certainly had some enemies. In the Rios book titled "Marcelo Rios: The Man We Barely Knew" Todd Woodbridge said that other players got up to play Rios, that they had extra incentive because of what an arrogant *****k he was. Gambill said Rios tried to stare him down in the player lounge before one match. But Rios also got along with certain other players like Berastegui, Koubek, Vicente, Lapentti, Di Pasquale, Joyce, Bjorkman, Henman, T Johansson, Spadea, Dent, Magnus Norman, etc. who all said they liked him and got along okay with him.
