( CNN ) -- With world No . 1 Novak Djokovic struggling at the ATP World Tour Finals , a tired Rafael Nadal exiting early , and third-ranked Andy Murray limping out of contention , the scene is set for renewed protests by tennis stars about their testing tournament schedule . But Roger Federer , perhaps the greatest of them all , has flatly rejected the notion that players should go on strike . `` It was brought up a few months ago , the whole boycott thing . It 's nonsense , '' the 16-time grand slam champion told reporters after clinching his third successive Group B win at the season-ending event on Thursday . `` It 's not going to happen anytime soon . Things are good right now , so I do n't see a reason why we should just boycott . There 's absolutely no reason for it . '' Can Federer make finals history ? Murray 's call for a players ' meeting before last month 's Shanghai Masters did not eventuate in any action , and the Scot himself later stated that he did not think a strike was necessary -- but that the issue of fixture scheduling needed to be addressed . Federer took a long break after the U.S. Open in September , while Nadal also had a rest with next month 's Davis Cup final between Spain and Argentina in mind .

But Federer is on course to become the first man to win the ATP championships six times after overcoming Mardy Fish 6-1 3-6 6-3 to eliminate the eighth-ranked American . The defending champion , who is president of the ATP Player Council , said a strike makes no sense . `` It 's not been an option really , in my opinion . Next year 's season is going to be shortened by two weeks , '' he said . `` That 's , I think , as much as we can squeeze it really because otherwise a lot of tournaments would have to go , or we would have four tournaments the same week , which I do n't think is a very smart idea , to be honest , for the game .
