Serbian tennis superstar Novak Djokovic has said that he thinks former World No.1 Roger Federer, who he faces on Tuesday at the ATP World Tour Finals, is noticeably slower on court.
However, the Serb said that the Swiss ace is never to be underestimated as long as he plays tennis since he has an incredible quality in his game.
This is the first year since 2002 that Federer has not made a Slam final and has drifted in the world rankings to seventh. Djokovic, who came from a set down to beat Federer in the semi-finals of the Paris Masters in Bercy on Saturday, was moved to comment with circumspection on Monday, the report said.
