text: do you think that anyone will ever de-throne roger federer as the tennis world number 1??   if federer continues to play beyond his prime (as sports figures sometimes do) , yes - he could get knocked off. but, as long as he continues to perform at full strength as he is now (despite his french open loss today to the "master of clay") i don't see it happening. if federer chooses to continue to play for a few more years, his uniform will forever hang from the rafters of ever major tournament site as the best player of all time. and that is saying a lot!
