Head coach Stuart Pearce controversially omitted the 37-year-old former England captain from his squad, for which he was allowed three over-age picks, the others being Wales duo Craig Bellamy and Ryan Giggs, who will captain the team.
Richards, however, insists that will not deflect his focus as the group prepares for the Friday's friendly with gold medal favourites at Brazil.
"No, I don't think there's any extra pressure because of that. You have to deal with pressure every time you play and, although this might be a little more special, I just want to go out and play my normal game," Richards said in the London Evening Standard.
"But I don't think it's really right for me to comment on what happened with David Beckham. That situation was totally down to Stuart Pearce. Obviously, when I didn't get selected for the Euros but got picked in the preliminary squad for Team GB I had one eye on coming here. Now all I can do is give 100% and show everyone why I am in the squad."
