Following his semifinal run at last year's US Open, Frances Tiafoe has been tipped to win a Grand Slam title in the near future by legendary coach Rick Macci.

The 68-year old praised Tiafoe's work ethic, talent and personality. Furthermore, Macci stated the World No.11 had a massive opportunity to win a Grand Slam, now that Federer, Nadal and Murray were retired or sidelined with injury.

"Fe Fi Fo, yes, I mean Francis Tiafoe. What a guy," said Macci. "Great personality, is a happy-go-lucky, great athlete. I love his imagination and his spirit. Now that he is there, he believes, and once you believe, you know you can achieve.

"With Federer and Murray and Nadal on the side now, people are going "why not me?" Francis is in the mix; he can grab a slam or two. I love his athleticism. And I love now how he's competing."

Macci revealed that Tiafoe occasionally trains at his academy, adding the best thing about the Maryland native was that he id a great human being.

"He comes to the park now and then," said Macci. "Just a great, great tennis player. But more importantly, a great human being.”
