Rafael Nadal beat fellow Spaniard Tommy Robredo on Sunday to retain the Open Seat Godo title and win a 47th straight match on clay.
Nadal overpowered 2004 champion Robredo 6-4, 6-4, 6-0 in 2 hours, 19 minutes to beat Bjorn Borg's mark of 46. Guillermo Vilas holds the record in the Open era on clay with 53 consecutive wins.
"I've achieved my main objective here, and I've overtaken Borg's number of wins and I guess I could try to go for Vila's total in Rome," Nadal said. "But I have my sights set on Roland Garros.
"You can't compare me to Borg. He was the greatest tennis player of all time. I can't see myself winning five Wimbledons."
However, 11-time Grand Slam champion Borg thinks Nadal could make a start this year.
"I congratulate Nadal," Borg said in a statement released by the ATP. "He's fun to watch and I hope he wins Wimbledon."
Nadal said: "I'm very happy, it's nice that he thinks I'm good to watch and I thank Borg for his kind words."
Nadal said he wanted to replicate last year's wins in Monte Carlo, Barcelona and Rome.
"It's not easy, the normal thing would be to not make it because as far as I know only Thomas Muster has won those three finals two years running," Nadal said.
Muster won the titles in 1995 and 1996.
Seventh-seeded Daniele Bracciali of Italy upset top-seeded Nicolas Massu of Chile 6-1, 6-4 to win the Grand Prix Hassan II tournament and his first ATP singles title.
"This win gives me a lot of confidence for the future. This doesn't happen to me every day," said Bracciali, who won a doubles title last year in Milan.
"I was serving very well and this helped me a lot. I expected a tough match and I'm happy that I got through and won my first title."
