ATP Finals London: Berrettini impressed by Djokovic

Although Matteo Berrettini suffered a clear defeat at the start of this year's Nitto ATP final against Novak Djokovic, the Roman can look back on an outstanding season. Until the beginning of 2018, Berrettini was a regular guest on the ATP Challenger Tour. By reaching the season finale in London, he became the first Italian since Corrado Barazzutti 41 years ago, this feat in singles succeeded.
