Roger Federer breezed past former champion Carlos Moya on Sunday to reach the quarter-finals of the French Open for only the second time.
The world number one was rarely troubled by the Spaniard, who went into the match with a shoulder injury that took the edge off his serve.
Federer broke at the first opportunity in each set and produced some sublime shots in a comfortable 6-1 6-4 6-3 win.
He goes on to face the unseeded Victor Hanescu of Romania in the last eight.
Federer admitted it was his intention to exploit Moya's weakness.
"He wasn't 100% - I knew how much pain he was in and that he couldn't serve so I had to make sure I got to him mentally."
Federer was knocked out in the third round in 2004 by an inspired Gustavo Kuerten and endured first-round defeats in 2002 and 2003.
He added: "It's a relief to be in the second week because I have had a few tough years in Paris.
"Now I want more. I feel as if I haven't used my reserve tank yet and that I have a lot of energy left."
