Nick Faldo hailed an "incredible" Rory McIlroy after the Irishman matched his achievement of successfully defending his Masters title.
The world number two also equalled Faldo's major haul of six and looks set to surpass it and become the most successful European of the modern era.
"All credit to him. Incredible. He’s got another major to his name," Faldo told Sky Sports.
"All he needs now is to win another US Open and another Open Championship and then he’ll be a two-time grand slam champion.
"That’s his goal. To get there along with the likes of Jack (Nicklaus) and Tiger (Woods).
"He’s unique. Rory is the only one out of those guys to go 11 years between wins, and then he’s added another one."
How it happened: Masters final day recap
Two-time Ryder Cup-winning captain Luke Donald was in no doubt about McIlroy's standing in the game.
"Tying Seve with 2 green jackets will mean a lot to Rory. He is undoubtedly the best European golfer of all time now. Congratulations," he wrote on X.
Paul McGinley, himself a Ryder Cup-winning captain and close friend of McIlroy, told Sky Sports: "McIlroy wants to be known as the best European of all time.
"As much as many of us might think that already, he still didn’t have as many major championships as Nick Faldo, nor Harry Vardon.
"Even though he’s caught Nick now with six, he’s still got Harry Vardon (seven) to catch.
"There’s always another level, and I think Rory has reset his goals in that regard."

Later, United States president Donald Trump called McIlroy a 'legend'.
Trump, who has played golf with McIlroy in the past, used his Truth Social platform to send a message to the 36-year-old.
"Congratulations to Rory McIlroy on another Great Championship, The Masters!" Trump wrote.
"He performed tremendously under intense pressure, something which few people would be able to even think about doing. With each year, Rory is becoming more and more a LEGEND!"
Trump then added a reference to the Cadillac Championship, which is expected to be McIlroy’s next appearance when it starts at Trump National Doral in Miami at the end of the month.
"I look forward to watching him compete in two weeks at Doral," Trump wrote.
"The quality of Professional Golfers today has become extraordinary, each and every one of them. They should all be proud of the way they played at The Masters this weekend!"
