Former world No. 25 Mischa Zverev believes Novak Djokovic, Daniil Medvedev, Alexander Zverev and Stefanos Tsitsipas are the new top-4.
For over a decade, Djokovic, Rafael Nadal, Roger Federer and Andy Murray were considered as the Big Four tennis.
Murray, Nadal and Federer have been battling injuries in recent years but Djokovic is still going strong.
Djokovic, Medvedev, Alexander Zverev and Tsitsipas are currently the four highest-ranked players in the world.
“From my point of view, the new top-4 are Djokovic, Medvedev, Sascha and Tsitsipas. That’s just my feeling, that can, of course, still change,” Mischa Zverev told Eurosport.
Mischa Zverev hopes Alexander Zverev reaches the No. 1 spot
Alexander Zverev had an outstanding 2021 season, winning six titles.
On Sunday, Alexander Zverev saw off Medvedev 6-4 6-4 to capture his second ATP Finals title.
Alexander Zverev has won at every level except the Grand Slam.
Alexander Zverev is currently enjoying a career-high ranking of No. 3 in the world.
Alexander Zverev’s goals in 2022 will be to win a maiden Grand Slam and climb up to the No. 1 spot.
“It is mathematically possible to become number one without a Grand Slam title, but it is very unlikely. In the last 20 years, I think only Marcelo Rios has managed to get to the top without a Grand Slam victory,” Mischa Zverev explained.
“There are people who win a Grand Slam but have never won a Masters. You can then say that it was a lucky coup, but if you’ve already won a number of Masters and twice the ATP Finals, then that’s not lucky.
“Sascha is one of the 10 players who have become world champions [ATP Finals] more than once. This list includes players like McEnroe, Borg, Becker and Sampras.
“From a purely statistical point of view, it should be enough for a Grand Slam victory. I don’t want to rely too much on the past, but rather see how Sascha can develop further in the future.”
