Having seen crowds return to a range of tour events, former Wimbledon winner Pat Cash understands the disappointment of tennis moving back to behind closed doors at the Olympic Games in Tokyo.
Each of the three grand slam events to have taken place this year has been held with fans in attendance, with Centre Court seeing capacity crowds for each of the singles finals at Wimbledon. The US Open, which begins on August 30, will allow 100 per cent fan capacity at Flushing Meadows for the final major of 2021.
However, Cash does not believe the lack of spectators at the Games will have too much of an impact on the players who have elected to travel to Japan.
"Well it's unfortunate that the Olympics won't have any fans. I think that's a real disappointment," Cash told Stats Perform.
"But 95 per cent of our life is played on an empty practice court and stadiums.
"Certainly, when you're coming through, nobody's watching you. It's only when you get to Wimbledon or something that you play with crowds, and they can make a difference. We've also been playing most of the year without them.
"To go back [to no fans] it's unfortunate, but it's not something unusual for the players. The crowd certainly does make a difference. It makes a difference with attention and with the crowd roaring and whistling or whatever they want to do."
World number two Naomi Osaka, who will return to action having withdrawn from the French Open to protect her well-being and subsequently skipped Wimbledon, is one athlete who could have benefited from the home support in Japan.
Though he is unsure of how boisterous the home crowd would have been in Tokyo, Cash still feels for the 23-year-old four-time Grand Slam winner.
"With no crowds there that's disappointing for her," he added.
"But you know, it's sort of something we've become used to on the tour - playing with empty crowds and the nerves still kick in, it is all about winning, and players tend to learn to block the crowds out quite well.
"They stay in their own world when they're on the tennis court. The urgency and the intensity of a match is not really going to change that much because the players really want this for themselves."
