Djokovic praises Murray: "He's an incredible competitor".

It's the hot topic of the moment: Andy Murray's imminent retirement.

Since the tribute ceremony organized in his honor on Thursday, testimonials praising the former world number 1 and two-time Wimbledon champion have been pouring in.

Novak Djokovic was in no short supply. At his press conference following his hard-fought 2nd-round victory (6-3, 6-4, 5-7, 7-5 over Fearnley), he returned to the subject of Murray: "When I first met Andy, I was 12 years old. Our history goes back many years. We may never have been very close on the circuit because it's very difficult, we're rivals, but we've always had enormous respect for each other. We've shared the best stadiums and tournaments for many, many years.

There's only a week's age difference between us, so our careers aren't that far apart. We've played some incredible matches, finals at every Grand Slam. He's one of the three players, along with Roger and Rafa, who have had the biggest impact on my career and my progression as a player. The fact that he is playing alongside his brother makes the event even more moving for everyone, for his family, for the tournament and for tennis.

I wish him all the best for his farewell, but I wouldn't be surprised if he decided to come back. He's an incredible competitor with a resilience that should be studied and taught to young athletes."
