Medvedev has won the US Open in 2021 and has reached the final of a Grand Slam for the sixth time. On the other hand, Sinner, who is participating in a Grand Slam for the 17th time, is the first Italian player to reach the singles final of the Australian Open. He is being compared to Federer who never reached the semi-finals in his first 16 Grand Slams and then won his first Grand Slam at Wimbledon.
