Despite winning as many as 8 Grand Slams as a player, Ivan Lendl wasn't satisfied, and he kept looking for ways to stay connected with tennis even after retirement.

Lendl took over as the coach of a player who had enormous potential but had tasted little success at the Grand Slam level - Andy Murray. The Czech had a big role to play in Murray's transition from being a Slam contender to becoming a Slam champion; he aided Murray in winning his first ever Major title at the US Open of 2012.

In 2013, he coached Murray to the Wimbledon title, thus enabling the Scot to achieve a lifelong dream. Their partnership initially ended in 2014 when Murray hired Amelie Mauresmo as his coach.

But the two re-kindled their relationship in 2016. Murray won the Wimbledon Championships and the Olympic gold that year, which helped him finish the year as World Number 1 for the first time.

Lendl currently serves as the coach of Alexander Zverev.
