Tsitsipas with a new racket: "I'm trying to adapt to the changes on the ATP Tour".

Stefanos Tsitsipas has been in poor form for several months. To compensate, the Greek has decided to try out a new racket.

During his match against Lorenzo Sonego in Dubai, he played with a racket that bore no logo of any brand, which could suggest the end of his contract with Wilson, his sponsor.

In a post-match interview, he was asked about this and admitted the changes: "I think it's obvious that in recent months there have been changes on the ATP Tour.

The players have talked about it a lot. There are players in the Top 10 who have talked about these balls becoming slower and slower, and I'm trying to adapt to that and take advantage of it.

I've had to deal with slow conditions over the last few months and I'm trying to change that uncomfortable feeling I've had recently."
