Andy Murray's trophy-filled career came to an end at the Paris Olympics on Thursday as another chapter closed on tennis's golden generation.

World number three Carlos Alcaraz edged closer to an Olympic Games showdown against Novak Djokovic on Thursday with a storming display which brought the queen of Spain to her feet.

World number seven Zheng triumphed 6-2, 7-5 and will face either Croatia's Donna Vekic or Anna Karolina Schmiedlova of Slovakia in the gold medal match.

Tearful Coco Gauff was dumped out of the Olympics Games tennis tournament on Tuesday in a stormy defeat to impressive Donna Vekic of Croatia.

Carlos Alcaraz shrugged off an injury scare to reach the last 16 of the Olympic singles tennis on Monday and said he will fight to be "100 percent" for doubles with Rafael Nadal.

Rafael Nadal said he will make a decision on his future in tennis "after the Olympics" in the aftermath of a shattering straight-sets defeat to old rival Novak Djokovic at the Paris Games on Monday.

It was 24-time Grand Slam champion Djokovic's 31st win in a rivalry which began on the same Roland Garros clay courts in 2006.

Rafael Nadal set up an Olympic Games blockbuster against old rival Novak Djokovic on Sunday, justifying his last-minute decision to play despite injury concerns.

"The important thing is that today he has warmed up, that he is ready to play," said Ferrer.

Matthew Ebden had not expected to last long against Novak Djokovic in the first round of the Olympics on Saturday and he was not wrong - but it left the Serbian wondering why the Australian doubles specialist was competing in the singles.

Carlos Alcaraz enjoyed a winning start to his Olympic Games career on Saturday when he swept aside Lebanon's Hady Habib.

Novak Djokovic lost just one game in his Olympic tennis opener on Saturday to set up a potential blockbuster clash against old rival Rafael Nadal.

Novak Djokovic says he has "high expectations" as he chases an elusive Olympic gold medal, with his confidence unshaken despite a poor year by his stellar standards.

Two-time Olympic gold medallist Andy Murray said he will not compete in the singles competition at the Paris Games and will prioritise the doubles event in the final tournament of his career before retirement.

The Italian said he was "sad and disappointed" to drop out, adding that he had started feeling unwell on Monday after a practice week in Monaco.

Nadal, the 2008 singles gold medallist, will pair up with Alcaraz in a tennis dream team at Roland Garros, looking to also add to the doubles title he won with close friend Marc Lopez at Rio in 2016.

The 37-year-old, a two-time Olympic champion, is planning to play in the singles and doubles at his fifth Games.

The 38-year-old Spanish left-hander has a protected ranking of ninth to put himself into the field for the Flushing Meadows fortnight, which begins on August 26.

"I don't have any limitations in my mind. I still want to keep going and play as long as I feel like I can play on this high level."

"So let's see if at the end of my career it's going to be 25, 30, 15, four (Slams). I don't know. All I want to say is I want to keep enjoying and let's see what the future brings to me."
