"You line up Djokovic, Federer and Nadal resumes, if you choose any of them except for Novak, you are an insane human," Andy Roddick

Andy Roddick has claimed that Novak Djokovic is the GOAT of tennis. The GOAT debate has been up for debate since a long time now, involving the likes of Rafael Nadal, Roger Federer and Novak Djokovic.

Andy Roddick picks Roger Federer as the toughest opponent he has ever faced, however, when it comes to the GOAT debate, he chooses Novak Djokovic. The Serbian has won 24 Major titles, with Federer winning 20 and Nadal winning 22. Novak recently lost in the Australian Open semifinals to Jannik Sinner in a bid to claim his 25th Grand Slam title.

"I saw prime Federer and it was the hardest matchup that I'd ever seen. He was the best player that stacked up against my game type so therefore, he's the last person I would want to play," he said.

"But you line up the three [ Novak Djokovic, Roger Federer and Rafael Nadal's] resumes, if you choose any of them except for this one [Novak], you are an insane human. Very simply, that’s the way it is. Everything else is about preference of what you like to watch," he added.
