One of tennis’ most dominant forces in the 1980s, Ivan Lendl, who turns 56, is on many people’s greatest of all-time list.

Originally from Czechoslokia before becoming a US citizen in 1992, Lendl helped usher in the era of “power tennis” with his strength and heavy topspin from the baseline. During his career, Lendl contested 19 grand slam finals – a record later surpassed by Roger Federer, Rafael Nadal and Novak Djokovic – and won eight of them.

Before the formation of the ATP, Lendl reached 12 year-end championships – a record he shares with John McEnroe. He reached the world No1 spot for the first time in February 1983 and held that ranking for a total of 270 weeks throughout his career.

He coached Andy Murray to his two grand slam titles in 2012 and 2013.
