The official, who had been accused of “losing his mind” by Novak Djokovic on Saturday when he penalised the Serb for pretending to hit a ball in his direction, issued a time warning to Nadal for slow play during the first set.

Courtside microphones picked up the nine-times French Open champion saying, “You can keep giving me those warnings but you are not going to be in the chair for me again.” But that did not stop Ramos from going further and removing a serve from Nadal in the third set for the same offence.

Afterwards, Nadal accused Ramos of having a particular fixation on him.

“I respect him a lot but it should work both ways,” he said. “I’m telling you this with some type of sadness, because I don’t want to have any problems. But this umpire is trying, in a certain way, to look for my faults, my errors. This is the impression I have.
