Ivan Lendl (born March 7, 1960) is a former world no. 1 professional tennis player. Originally from Czechoslovakia, he became a United States citizen in 1992. He was one of the game's most dominant players in the 1980s and remained a top competitor into the early 1990s. He is considered to be one of the greatest tennis players of all time. Lendl captured eight Grand Slam singles titles. He competed in 19 Grand Slam singles finals, record surpassed by Roger Federer in 2009. He reached at least one Grand Slam final for 11 consecutive years, a record shared with Pete Sampras, with the male primacy of 8 consecutive finals in a slam tournament (a record shared with Bill Tilden at US Open). Before the formation of the ATP Lendl reached a record 12 year-end championships (equaled by John McEnroe). He won two WCT Finals titles and five Masters Grand Prix titles, with the record of 9 consecutive finals. He also won a record 22 Championship Series titles (1980–89) the precursors to the current ATP Masters 1000. Lendl first attained the world no. 1 ranking on February 28, 1983 and bolstered his claim to the top spot when he defeated John McEnroe in the 1984 French Open final. For much of the next five years, Lendl was the top ranked player until August 1990 (with a break from September 1988 to January 1989 when Mats Wilander was at the top). He finished four years ranked as the world's top player (1985–1987 and 1989) and was ranked no. 1 for a total of 270 weeks and set a new record previously held by Jimmy Connors, since broken by Pete Sampras and Roger Federer. In 2011 he became Andy Murray's coach.

John Patrick McEnroe, Jr. (born February 16, 1959) is a former world no. 1 professional tennis player from the United States. During his career, he won seven Grand Slam singles titles (three at Wimbledon and four at the US Open), nine Grand Slam men's doubles titles, and one Grand Slam mixed doubles title. McEnroe also won a record eight season ending championships, comprising five WCT Finals titles and three Masters Grand Prix titles from twelve final appearances at these two events, a record he shares with Ivan Lendl. He posted the best single season win-loss record in the Open Era in 1984 at 96.47% (82/3). In addition he won 19 Championship Series top tier events of the Grand Prix Tour that were the precursors to the current Masters 1000.

He is best remembered for his shot-making artistry and superb volleying; for his famous rivalries with Björn Borg, Jimmy Connors and Ivan Lendl; for his confrontational on-court behavior which frequently landed him in trouble with umpires and tennis authorities; and for the catchphrase "You cannot be serious!" directed toward an umpire during a match at Wimbledon in 1981. He was inducted into the International Tennis Hall of Fame in 1999, and is regarded as one of the greatest tennis players of all time.

Andrew "Andy" Murray (born 15 May 1987) is a Scottish professional tennis player, ranked No. 4 in the world, and was ranked No. 2 from 17 to 31 August 2009. Murray achieved a top-10 ranking by the Association of Tennis Professionals for the first time on 16 April 2007. He has been runner-up in three Grand Slam finals: the 2008 US Open, the 2010 Australian Open and the 2011 Australian Open, losing the first two to Roger Federer and the third to Novak Djokovic. In 2011, Murray became only the seventh player in the Open Era to reach the semi-finals of all four Grand Slam tournaments in one year.

Andy Murray was born to Will and Judy in Glasgow, Scotland. His maternal grandfather, Roy Erskine, was a professional footballer who played reserve team matches for Hibernian and in the Scottish Football League for Stirling Albion and Cowdenbeath. Murray's brother, Jamie, is also a professional tennis player, playing on the doubles circuit. Following the separation of his parents when he was nine years old, Andy and Jamie lived with their father. Murray later attended Dunblane High School. Murray is in a five-year relationship with Kim Sears, who is regularly seen attending his matches. The relationship ended briefly in 2009 before they reconciled a short time later in 2010.
