Mats Willander (Sweden)
Often underrated tennis player when players like McEnroe, Connors, Becker around but mind you Mats Willander has won seven Grand Slam titles and out of which three he won in a single year. Willander has even won one doubles Grand Slam before getting retired in 1996. Like Lendle for Willander too Wimbledon remained elusive as he won US Open once and Australian Open and French Open thrice. Willander did won a Wimbledon title in doubles in partnership with Joachim Nystrom.
Boris Becker (Germany)
He is probably one of those few players who was adored by the Wimbledon crowd. He was the youngest to win the Championship at the All England Lawn Tennis Courts. Boris Backer won three Wimbledon titles along with one US Open and two Australian Open titles. Boris Becker won the Olympic Gold Medal too. The only Grand Slam Becker could not won was The French Open.
Andre Agassi (USA)
On the field they were fierce rivals but off it they were buddies. Andre Agassi and Pete Sampras met five times in Grand Slam finals and Agassi was lucky only once. But this is not enough to get the idea how Agassi ruled the tennis courts across the world. He has managed to win all four Grand Slams during his entire career. He has won Wimbledon, The Australian Open and the French Open once and won the US Open twice. Hence no one can question his all round abilities for sure.
Pete Sampras (USA)
This silent American on the tennis court holds so many records in men’s tennis. It is not easy to find Sampras in anger or making any argument against line umpire or even with referees. Sampras holds the record of winning the most number of Grand Slam singles titles ever. All in all Sampras has won 14 Grand Slam titles and yet it is really unbelievable to know that Sampras could never win the French Open which is played on the red clay court. Sampras has won Seven Wimbledon titles (Four in a row), Five US Open and Two Australian Open. Apart from winning all these titles Sampras was also holding a record of No. 1 money earner of all time in the game of tennis.
