Australian maverick Nick Kyrgios is ready to win over his doubters and can become an ‘international sporting superstar’ according to former world number one Boris Becker.

“There has never been a question mark over his talent but there was a question mark about his discipline,” Becker said.

“But he’s getting it together now. It would be wonderful to see him get to the quarters or semi-finals.

“He’s not as clean cut as some Australians would like to see. But he could be an international superstar in sport, with his multi-ethnic background, his style, the ear rings.”
