A year after Bjorn Borg wrote off Roger Federer's chances of capturing the 2008 Wimbledon title, the Swedish great put once again the Swiss as top favor to the All England Club title.

Borg tipped Rafael Nadal to win the grasscourt major 12 months ago and despite being proved right, his comments did not go down well with Federer.

But after the Swiss completed his collection of grand slam titles by triumphing at Roland Garros nine days ago, the Swede has once again switched his allegiance.

"Coming into Wimbledon I think he is relieved in a way that he won Paris, because that was one of his main ambitions, goals to try and win Paris," said Borg, who shares with Federer the professional era record of winning five successive Wimbledon titles.

"So coming into Wimbledon he feels very confident, he has equalled (Pete) Sampras's record of 14 grand slams.

"We all know how Roger is playing on the grass, he plays unbelievable tennis on the grass. I think he is going to have a big challenge from Andy Murray, if I have to pick up two guys for this year's Wimbledon I would pick Murray and Federer."

Federer's success in Paris made him only the sixth man to win all four majors. According to Borg, that put Federer on the summit when it came to deciding who was the best of all time.
