Rafael Nadal has accused Nick Kyrgios of “lacking respect” after the Spaniard was dumped out of the Mexican Open by the controversial Australian, as reported on the Irish Independent.

Kyrgios overcame Nadal 3-6 7-6 (7-2) 7-6 (8-6) in the second round of the tournament and the Spanish international was not happy with some of the tactics used by his opponent.

Late in the match, Kyrgios began to use an underhand serve which made Nadal furious, but eventually, after three hours of competing, Kyrgios sealed the win. 

Nadal said:

He lacks respect for the public, the rival and himself. 

He’s a player who has the talent to win Grand Slams – a player who can fight for the top rankings, but there’s a reason he is where he is. 

He is a very dangerous player but lacks consistency, I don’t think he’s a bad guy. I think he’s a good guy.

The 23-year-old was booed by the fans for his tactics but he has defended himself, saying that Nadal should be angry at himself for not being able to deal with him. 

Kyrgios has advanced to the semi-finals after being Stan Wawrinka.
