Boris Becker has revealed he's "still close" to Novak Djokovic after the 12-time Grand Slam champion chose Andre Agassi to succeed the German as his coach.
Becker, 49, guided Djokovic for three years before they parted ways late last year -- and the Serb took his time before confirming Agassi as the man helping him prepare for a defence of his French Open crown.
"We're still close, we still talk a lot. I heard the name Agassi for a while and I think it's a good choice," Becker said.
"Ideally you don't want to start at the French Open with a new partnership. You want to start a few weeks before, so I hope, and they're both experienced, that they click quickly. Andre's tennis expertise are second to none and I think their personalities would fit.
"Interestingly enough Andre won his most important titles late in his career and I think that's another point that fits -- Novak has obviously won everything in his life, but is looking for new inspiration and he can talk to a guy who won most of his grand slams in his thirties."
While Becker -- a six-time Grand Slam winner himself -- approves of Djokovic's alliance with Agassi, he's less confident the part-time nature of Andy Murray's relationship with coach Ivan Lendl will yield success.
World No. 1 Murray has endured a torrid start to 2017 with early exits at the Barcelona Open and the Italian Open and Becker believes his former rival Lendl needs more time on the practice court with the Scot.
Becker said: "Am I surprised he [Lendl] hasn't been around more? A little bit.
"When I first asked to work for Novak, the original idea was the grand slams only and I said, 'I don't think that is possible. I have to see you more than just a couple of days before grand slams to know where you are. I have to know the ups and downs and really get to know you in lesser tournaments'.
"So I told him, 'If I am going to do that, I have to be with you more'. But that is their arrangement.
"That is what worked last year, that was part of the deal. But I think, if both were honest, the gap between Melbourne and the French was maybe a little long."
