Wimbledon/Men's singles: Juan Carlos Ferrero has tipped Sebastien Grosjean to end Tim Henman's dreams of Wimbledon glory at the quarter-final stage.

Grosjean will face the British number one in the last eight on Centre Court today after seeing off the challenge of French Open champion Ferrero.

The 13th seed secured a 6-2, 4-6, 7-6, 7-6 victory on Court One in a fourth round match held over from Monday night when bad light halted play with the Frenchman leading two sets to one.

It gives Henman the chance to gain revenge for his straight-sets defeat to the Frenchman in the semi-finals of the Stella Artois Championships last month.

But Ferrero witnessed at first hand how dangerous Grosjean can be and said: "I think he has a lot of chances to win because he is returning very well.

"He has a lot of potential in his shots. He has a very good forehand, very good serve and when he's (playing) with confidence he's a difficult guy to beat.

"I was playing very well this Wimbledon and maybe if I had a little more luck I would have won the match and been in the quarter-finals, but Grosjean was playing better than me."

Grosjean also played much better than Henman at Queen's and feels he has nothing to lose against the home favourite, who carries the hopes of a nation on his shoulders once again.

"I know everybody will be for Tim," said Grosjean, who practised with Henman last week at the All England Club. "He has a really good chance to win this year, but I will try my best to play a good game.

"I played him on Centre Court four years ago and although the crowd was for Tim (who won in four sets) it was good, I didn't feel everybody was against me.

"Tomorrow may be different, but I will focus on myself and not think I have Tim against me. Always when you play at home you have pressure, but it's the same for us at the French Open.

"It's going to be difficult for both players but I have nothing to lose. I am really happy to be in the last eight for the first time here."

Grosjean won 6-3, 6-4 at Queen's before losing to Wimbledon favourite Andy Roddick in the final, and knows a repeat of the same tactics could prove fruitful.

"It's always good to beat a player 10 days before you have to play him again," added the 25-year-old, who was born in Marseille but is now based in Florida.

"At Queen's I returned well and I will have to do so again. He did not serve as well, maybe he was feeling his shoulder. But I played good there."

It looked as though Henman, already through to the last eight with victory over David Nalbandian on Monday evening, would be forced to wait a little longer to discover his opponent when Ferrero broke serve to take a 3-1 lead in the fourth set.

The French Open champion served two double faults in the next game, however, to help Grosjean break straight back and he levelled the scores at 3-3 by holding serve comfortably.

Ferrero was aiming to become the first Spaniard into the quarter-finals for 31 years but could be forgiven for thinking everyone was against him during the later stages of what proved to be the final set.

A drop shot from the third seed clearly bounced twice before Grosjean retrieved it, and Ferrero attempted to play the next shot through his legs thinking he had won the point.

Umpire Lars Graff, in charge of the controversial Greg Rusedski v Andy Roddick second round match, was apparently the only person on Court One who had not seen it, however, and initially awarded the point to Grosjean.

Ferrero was already walking back to the baseline to serve but turned round in amazement and began to argue with Graff, who took some persuading to ask Grosjean what happened.

To his credit, the Frenchman admitted it had bounced twice - unlike Henman against Nalbandian - and was warmly applauded by Ferrero and the crowd for his sportsmanship.

"It was very good of him, he is a nice guy," said Ferrero, who then held serve to lead 5-4 despite another debatable line call which Graff declined to overrule.

But he was broken in the 11th game due to two uncharacteristic unforced errors.
