On the video he said what he said to Roger when the match was over..
they congratulated each other of the match, and delpo said to roger than the tournament was all for him to win, and on sunday he will be watching the swiss triumph.. then roger congratulates him of the great tournament
He was right to be frustrated, he could've won that match. I like that he doesn't try to sugarcoat his disappointment (unlike Soderling who was such a Federer groupie after the RG final but moving on lol).
His look at the :36 mark is scary though. He looks like he's ready to punch someone.
