Sa inspired by Ronaldo for clash with Briton

After Michel Kratochvil, another little-known non-seed stands in Tim Henman's way. Is the Brazilian Andre Sa worried? Not a bit.

Sa is enjoying the flush of his country's sporting success elsewhere and is gaining confidence in his own ability which has taken the 25-year-old to his first quarter-final in any grand slam. Admittedly he was not sure of his opponent's identity when questioned, but he insists he has "a zero" fear of whoever he plays tomorrow.

"Once in the quarter-finals," he said, "Everybody is playing well, everybody has their confidence very high. So it is just a matter of who wants it more."

The Brazilian wanted it more yesterday than Feliciano Lopez in their fourth round match, even if the young Spaniard grunted and groaned much louder. Sa won 6-3, 7-5, 4-6, 6-3 and it was a surprise, given Lopez's grand stroke looseness, that it went to four sets.

Lopez, playing his first senior grass-court event, had superior power of serve but markedly inferior control; he made nearly three times as many unforced errors as his conqueror. Sa's soundness is scarcely eye-catching but Henman in his erratic form must beware; the Brazilian made just nine unforced mistakes in the match.

Sa's progress, in this summer of sporting shocks, has defied the form book. He came into Wimbledon having suffered five successive first-round defeats. In his four previous visits here, he had overcome his opening match only once.

He is ranked the world No90 and is a classic clay-court player. But Sa is in the mood for grass success.

"I looked at Ronaldo's picture today in the paper and I said, 'I hope I have the same face as he does at the end of the day'. That just happened right now."
