NEW YORK • While a host of young rivals hope to disrupt the dominance of the "Big Three" in men's tennis, Novak Djokovic, Rafael Nadal and Roger Federer again remain the US Open favourites.
The year's final Grand Slam starts tomorrow on the Flushing Meadows hard courts with top-ranked Djokovic, Federer and Nadal having won the past 11 Slams.
But 20-time Grand Slam champion Federer does not see a problem with the dominance by the trio, who together own 54 of the past 65 Slam crowns.
"I don't think it's a problem," said the 38-year-old, who is refreshed after a family caravan vacation around the Swiss countryside to get over his heartbreaking Wimbledon final loss to Djokovic last month.
"Now that Novak, Rafa and me are healthy again, Andy (Murray) also slowly coming back again, it has made it much harder for young guys to come through.
"They are definitely knocking on the door. I think that's very encouraging for those who want to see somebody else win.
"But I think also Novak's domination, Rafa's domination is also not normal for the game. It seems like the same guys are the favourites again this time around. It will be a surprise if anybody else won."
Third seed Federer also throws in a chance for Swiss compatriot Stan Wawrinka, who, like Britain's injured Murray, has won three Grand Slam. The 34-year-old Wawrinka was also the last player besides the "Big Three" to have won a Slam title - in New York in 2016.
Defending champion Djokovic, seeking a 17th Slam title, has won four of the past five major tournaments, denied only by Nadal's 12th French Open win in June.
Although no men's champion has retained the US Open crown since Federer in 2008, Djokovic can take encouragement from a fine run in recent years.
Apart from 2017, when he missed out through injury, the Serb has reached at least the semi-finals every year since 2007.
The 32-year-old says he has adjusted to the extra pressure of defending over the years.
"It's a paramount challenge to defend a Grand Slam title," Djokovic said. "These are the tournaments you want to win the most. This is where you want to shine."
The 33-year-old Spaniard Nadal has made an impressive run with titles in Rome, Roland Garros and Montreal and a Wimbledon semi-final loss to Federer.
"Arrive to the big events with good feelings helps," said the 18-time Grand Slam winner.
"Positive feeling helps for the confidence. For the moment I am feeling well. I am practising well during the whole week, I will push a little bit more and try to start the tournament in a good way."
Among the youngsters trying to make a breakthrough is 23-year-old Russian Daniil Medvedev, who has enjoyed a stellar US Open run-up that included beating Djokovic en route to winning the Cincinnati Masters last week.
Germany's sixth-ranked Alexander Zverev, 22, highlighted the threat of Japan's seventh-seeded Kei Nishikori, 29, the 2014 US Open runner-up, and Greece's eighth-ranked Stefanos Tsitsipas, 21.
"There are a few guys that have a real shot to win it," Zverev said.
"Obviously the 'Big Three' we don't need to talk about. But there are other guys that have been playing great tennis and will be able to do some damage."
