Ivan Lendl - 8-time Grand Slam inner

Ivan Lendl's story is one of pure grit and determination, and a lot can be learned from his success on tour. His career is inspirational in many ways, but what truly makes his career special is that his first Grand Slam triumph came after he had finished runner-up on four different occasions.

Lendl won eight Grand Slam titles and 94 singles titles overall, and stood at the top of the ATP rankings for a total period of 270 weeks. He had as many as eight stints at the top of the ATP rankings, starting from 1983 and culminating in 1990.

The Czech's longest stay at the summit of the rankings was from 5 September 1985 to 11 September 1988 - just over three years. During this spell, Lendl won six of his eight Grand Slam titles.

Lendl's longest consecutive period at the top lasted 157 weeks.
