The match hasn't been as great as the 2 previous ones from Richard. But he's won and will play the final, that's what counts.
He has admitted it himself when interviewed, right at the end of the match. He said that Rochus was exhausted and that he hasn't played a great match, unlike the last ones. He's been strong enough to be efficient on the important points and is looking forward to the final. When asked what was different in him with how he was last year, he smiled, said it was a tough question, and simply responded that he was more serious now -understand whatever you want!- and totally ready to work as hard as required to reach the top.
