Stan Wawrinka is a stalwart in what was undoubtedly the toughest period to be a male player on the ATP Tour.
After all, he was regularly forced into contact with three legendary figures who swiftly established themselves as the greatest in the history of the sport.
First came Roger Federer, followed shortly after by Rafael Nadal. Then, Novak Djokovic emerged to spoil the party.
And yet, so often when discussing the rise of the Big Three, Andy Murray goes criminally unmentioned.
Stan Wawrinka compares Andy Murray to Alcaraz and Sinner
Asked by Amazon Prime to choose between the two players they put forward, Wawrinka was as magnanimous as ever.
After all, the very first clash saw himself pitted against Juan Martin del Potro, to which he promptly picked the Argentine.
Then opting for Lleyton Hewitt over Del Potro, he swapped the Aussie for Murray as soon as the opportunity arose.
This is where he got the chance to compare the old with the new, not hesitating when picking the 38-year-old over Jannik Sinner, David Ferrer, Jo-Wilfried Tsonga, Dominic Thiem and Marat Safin.
However, when Carlos Alcaraz came up, he made a shock change, preferring the four-time Grand Slam champion to Murray.
