Federer, Nadal and Djokovic warned of new future GOAT who could break all records

Roger Federer, Rafael Nadal and Novak Djokovic have been warned that their GOAT status is under threat from Carlos Alcaraz. Renowned tennis coach Rick Macci, who spotted the likes of Serena and Venus Williams when they were teenagers and saw them transform into Grand Slam champions, claimed the 19-year-old was the best player he had seen in 40 years.

And he has now claimed that Alcaraz will exceed the Big Three of Federer, Djokovic and Nadal as the best talent he had seen in decades.
