#2 Rafael Nadal
Rafael Nadal lived up to his 'King of Clay' nickname as he won eight French Open titles in this decade. None of the players could touch the Spaniard at his favorite event as he maintained his winning streak for a long time.
The left-handed player took his Grand Slam tally from 6 to 19 in the last 10 years.
Apart from the French Open, he also won three US Open titles. His most recent triumph there came in 2019 as he defeated Daniil Medvedev in the finale.
Although the Spain-born superstar has spent 158 weeks in the decade at the number 1 position, he was unable to win a single ATP Finals competition.
#1 Novak Djokovic
Just like all the other stars present on this list, Novak Djokovic also took a break from tennis to deal with his injuries. However, he came back from the hiatus with aplomb, reaching the No. 1 ranking again after slipping out of the top 10.
When the 2010s decade commenced, the Serb had only won one Grand Slam championship. However, he decimated most of his opponents over the next 10 years to establish his supremacy in the sport.
Djokovic now has 16 Grand Slams to his name, and he also won four consecutive ATP Finals events this decade. He held the number one rank for 275 weeks, and with 6 Australian Open and 3 US Open wins, he proved that he is the king of hardcourts.
