Mats Wilander made an interesting comparison between the teenager Denis Shapovalov and two legends of men's tennis. The 1988 US Open champion commented on Shapovalov's big potential in an interview to Reuters. 'He is a serious talent.

To be 100 percent honest, you cannot compare Shapovalov to any other youngster. He is a completely different level. It’s like watching a combination of Nadal and Federer at 18 years old. He has the fire of Nadal and the speed around the court of Nadal and he has the grace of Federer - it’s unbelievable.

He really captivates the crowd. Last night it was like ‘Oh my god, where does this kid come from?’ He flies. I’m really really impressed. The best players in the world better watch out for him now.' Last month Shapovalov beat Juan Martín del Potro and Rafael Nadal among the others to reach Montreal semifinals and now at the US Open, starting from the qualifying draw, he reached third round winning five matches.
