Diaz, who has two years left to run on his contract at Anfield, attracted interest from Manchester City last summer and also has admirers in Saudi Arabia.
“I’m very happy at Liverpool – I’ve always said so,” said Diaz when on international duty earlier this summer.
“The transfer market is opening, and we’re trying to arrange what’s best for us. I’m waiting to see what happens.
“If Liverpool give us a good extension or I have to see out my two-year contract, I’ll be happy. It all depends on them. I’m here to decide and see what’s best for us and the future.”
Meanwhile, Liverpool have confirmed former Netherlands international Giovanni van Bronckhorst will be joining the club as an assistant coach to manager Arne Slot.
Van Bronckhorst succeeds John Heitinga, who left the Premier League champions to become the head coach at Ajax.
Fifty-year-old Van Bronckhorst, who played in the Premier League for Arsenal, has managed Rangers, Besiktas and Feyenoord.
