Intro After my 5 football statistics books, I decided to publish a tennis statistics one, as well. So, this is my 6 th (statistics) book, overall. It's about the 3 of the biggest rivalries in tennis history (the present one, between Roger Federer, Rafael Nadal, Novak Djokovic and Andy Murray, or the so-called ''The BIG 4'' of tennis), the ''Pete Sampras vs. Andre Agassi'', the greatest tennis rivalry during the 1990's, and undoubtedly one of the most important and spectacular of all time, and also about the greatest rivalry of the late 70's, and early 80's, the one by Bjorn Borg, the greatest clay-court champion (with 6 French Open titles) until Rafel Nadal (who has won an astonishing 13 French Open titles), and also a grass-court legend (with 5 Wimbledon titles to his name, winning them all consecutively, just like Roger Federer, later on), until being surpassed by Pete Sampras (with 7 titles), and later by Roger Federer (with 8) and Novak Djokovic (with 6), vs. John McEnroe, his greatest rival. The last part consists of some Roger Federer career stats, ''The Swiss Maestro'' stil being considered by many as ''The G.O.A.T.'' (or the Greatest Of All Time), as well as the list of all the active players who have won and/or have played at least one Grand Slam or Masters 1000 final. Tennis - ''The white sport'' - By far, the most intense, entertaining and beautiful to watch! All the information about the active players: as of July 2021 (after the 2021 Wimbledon Championships)
