“He's the only one I ever would have done it for“
Muster was team Austria’s captain at the ATP Cup, which is where talks were consolidated with Thiem.
The world No.4, who prevailed in one of three ATP Cup matches in Sydney, will continue to work alongside Nicolas Massu in 2020, but Muster will also contribute for 20 weeks this year.
Muster feels it is a privilege to be offered this opportunity and believes they can propel Thiem to the top of the game.
“If I can achieve with him to be No. 1 and to win a Grand Slam, I think he's the only one I ever would have done it for, because to have an Austrian who has that opportunity, you have to kind of commit yourself. It's almost a must,” Muster told ATP.com.
“It is an honour that a player like Dominic is looking back at me and saying, ‘Well, there could be some help for me.’ And I'm happy to put all my knowledge and my experience that I had all those many, many years playing tournaments if I can add some value to his game.”
