Roger Federer has opened up about wife Mirka in a revealing insight into the most famous WAG in world tennis.

Roger and Mirka are arguably the most-loved couple in tennis, with fans swooning over their relationship.

Mirka was a budding tennis player before meeting Roger at the 2000 Olympics in Sydney, before a number of debilitating injuries forced her to retire.

“My wife Mirka has suffered a lot due to her physical problems,” Federer said in an interview with Ringier.

“Her career ended very early and I myself advised her to end that pain.

“I told her as if it were the simplest thing in the world.

“Looking back on it today, I get a weird feeling. I am still playing tournaments at 40 and I find it difficult to stop.”

Federer also revealed a funny anecdote about when Mirka called him in the middle of a match.

“She once phoned me while I was in the middle of a game,” he recalled.

“She had completely forgotten that I was playing.

“This is exactly what I like about her. When we are in a tournament, she is 100% involved, while at home she is free from all thoughts.”

Roger and Mirka have been married since 2009 and have two sets of twins together – Myla and Charlene and Leo and Lenny.

After retiring from tennis in 2002, Mirka went on to serve as Federer’s manager for a brief period before having children.

Mirka and the kids are often spotted courtside at Federer’s matches, cheering on the Swiss legend.

Meanwhile, Federer will almost certainly miss the Australian Open for the second year in a row, with the Swiss maestro said to be recovering slowly from a third knee surgery in 18 months.

Federer’s long-time coach Ivan Ljubicic has played down fears the tennis world has seen the last of the 20-times grand slam champion, who turned 40 in August.

Federer has played just 13 matches in 2021 and not one since suffering a straight-sets quarter-final loss to Hubert Hurkacz at Wimbledon in July.

The six-time Open champion’s latest four-month lay-off comes after he spent a year on the sidelines following his record-setting 15th semi-final appearance at Melbourne Park in 2020.

“He is 40 and doesn’t recover as fast as before. But he wants to compete again and won’t retire all of a sudden.

“We will be able to see Roger again next year. I don’t know when exactly, but he is undergoing rehabilitation. He is recovering slowly, he is not in a hurry.”

The veteran superstar was still on crutches when he made a surprise appearance courtside at the Laver Cup in Boston in late September.

“Given that he was still on crutches, I doubt we’d see him here because he needs a longer prep to get ready for a grand slam than what he’s going to be able to have,” Australian doubles great turned commentator Todd Woodbridge told AAP.

Federer contested a record 21 successive Opens from 2000 to 2020 and boasts a remarkable 102-15 win-loss record at the tournament.
