Russia also boasts two former number 1 men's players—Safina's older brother Marat Safin and Yevgeny Kafelnikov. Russian men currently in the top 50 include Daniil Medvedev, Andrey Rublev, Aslan Karatsev and Karen Khachanov. The Russian men won the ATP Cup in 2021. Medvedev has been using the German transliteration (medwed33 or daniilmedwed) on his social media accounts, Rublev has chosen to simplify his surname in Latin script — like Vera Zvonareva has done — by dropping the umlaut.
