Never in the history of tennis where you have a pair of most dominant players(Federer/Nadal) ever to play the game. Borg/Connors, Pete/Andre or Laver/Rosewall were good too but they fall short.
Tier1(goat): Federer; Tier 1.5: Laver, Gonzales, Sampras, Nadal, Borg;
Tier 2: Lendl, Connors, Rosewall, Tilden; Tier 2.5: McEnroe, Agassi
