Is Fed still the best?

By the Swiss master's high standards 2008 has been a disappointing year, although he did end it on a high by winning the final grand slam of the year, beating Britain's Andy Murray in the US Open final. He lost his status as the world No. 1 to longtime rival Rafael Nadal two months ago but his latest US Open title ? his fifth in succession ? puts him just one behind Pete Sampras' record of 14 major championships. So is Roger Federer still the best tennis player on the men's circuit, or has the mantle been passed over for good? Have your say!
