Andy Murray says being a good dad is his top priority now

Andy Murray says his top priority is trying to be a good dad following the birth of his daughter Sophia Olivia.

The British number one is preparing to help Great Britain begin their Davis Cup defence against Japan this week.

Ahead of the tie, Murray told ITV News he hadn't given much thought to how the birth of his daughter would affect his appetite for success on court, but if it had a negative impact "that's fine".

The 28 year old has not played since losing the Australian Open final to Novak Djokovic at the end of January in order to spend time with his new daughter, who was born on February 7, and wife Kim Sears.

"My family is the most important thing to me now," he said.

"If it has a positive impact fantastic, if it has a negative impact that's fine as well.

"A lot of players have gone through it and everyone deals with it differently."

Murray said he has been enjoying fatherhood so far and that it had been "tough" being away from his daughter for the first time as he prepares for the Davis Cup tie.

"The first day was great," he said. "The scariest part for me, rather than exciting, was when I was left alone with her for the first time.

"It's been tough being away from her the last few days. It had to happen at some point I guess."
