Sinner: "Berrettini is someone who means a lot to me".

Jannik Sinner is happy. Having enjoyed an exceptional season, the Transalpine dominated the circuit all year long and even succeeded in crowning it all with a world title for his nation in the Davis Cup.

Far from taking all the credit, the 23-year-old was keen to pay tribute to his Italian partners, and in particular to one of them: Matteo Berrettini.

Absent from last year's tournament, the Italian colossus was just as important as the world No. 1 in his conquest of the Davis Cup crown.

Highly complimentary, Sinner explained: "It's been a crazy year, and I'm very proud of the whole team. There's a lot of hard work behind it, and I'm really pleased to have won the Davis Cup again. Last year, Berrettini wasn't able to play, so it's nice to share this special moment with him too.

Matteo is a person who means a lot to me, and I'm honoured to be part of it all. Today's match (Sunday) wasn't easy, Griekspoor played very well. I'd also like to say a few words for Koolhof (the Dutch doubles player), who won't be able to say goodbye to tennis on the court.

He's had a crazy career, I wish him all the best for his future, he's a beautiful person."
