Short video of Richard yesterday...
He says... even though he lost, he played well against Del Potro and thinks that will continue. Federer is a great player, he's the favourite, especially indoors, but he (Richard) will try his hardest and try to play a big match. He needs to serve well, return well and be aggressive to win.
He's looking relaxed though, he's done so many interviews and photo sessions this week, he actually looks quite calm around the media in this video.
