Tennis legend John McEnroe has tipped six young players to challenge the 'Big Four' of Roger Federer, Rafael Nadal, Novak Djokovic and Andy Murray for Grand Slams within the next 24-months.
Collectively, the 'Big Four' have 51 Grand Slam titles between them, with the dominance of Federer (20), Nadal (16) Djokovic (12) and Murray (3) has seen them all clean up consistently since 2005, during a period where only Juan Martin del Potro, Marin Cilic and Stan Wawrinka have put a slight scratch on their supremacy.
But the American seven-time Grand Slam winner McEnroe believes that all that is going to come to end in the next two years.
And he named Kyle Edmund, Alexander Zverev, Denis Shapovalov, Borna Coric, Stefanos Tsitsipas and Felix Auger-Aliassime as the candidates to do the job.
"It’s so wide open for that Next Gen," McEnroe said, per The Metro. "Who’s going to step up and win multiple majors?
"We're going to finally get an answer in the next 24 months for me. For sure."
Briton Kyle Edmund is currently ranked 17th in the world and despite not winning any singles titles to date, he does have a double career title to his name with Cameron Norrie at Estoril. He is a powerful player and moved up in people's estimations after beating Novak Djokovic in May at the Madrid Open as well as reaching the semi-finals of the Australian Open.
McEnroe does have a slight concern regarding Edmund, though and when questioned who of the next generation looks most likely to win a Grand Slam first: "It depends at what age we’re starting from. Edmund, is he too old at 23?
"Zverev would be the logical choice, even though he’s choked in the majors so far.
"I like Shapovalov a lot, I think he’s going to do big things."
Alexander Zverev would appear to be in the position currently and has a good record for a young player, winning three Masters 1000 titles by beating Djokovic, Federer and Austrian Dominic Thiem in the final.
Elsewhere, McEnroe was more dismissal of his young compatriot Frances Tiafoe's chances but thinks the likes of Borna Coric, Stefanos Tsitsipas and Felix Auger-Aliassime all have the potential to succeed in the marquee events.
"Coric, if he stays healthy on a slower court, he remains dangerous.
"I think he’s (Tiafoe) behind those guys.
"Another Canadian Auger-Aliassime – this young kid, he’s going to be really good.
"I like the young Tsitsipas, the young Greek player – he’s a tough customer."
