“Each has their own story, all three have achieved incredible things and also have different records,” Thiem’s coach said.
“I put them on the same level, talking about the three of them is talking about an example of everything, each with their own personality.”
Massu’s player Thiem became the first person outside of the big three to win a Grand Slam since Stan Wawrinka at the 2016 US Open, when he captured the title in New York himself last Autumn.
The Austrian has also managed to beat all three players while working under his Olympic champion coach.
