World No.1 Andy Murray has revealed he had not immediately accepted his knighthood, amid worries of a negative impact on his tennis career.

Murray was announced as the recipient of a knighthood in the New Year's Honours list, capping his best year in which he won Wimbledon for a second time, retained his Olympic title and topped the world rankings for the first time.

But at age 29, the Scot has plenty of time to add to his growing list of accomplishments and he had been concerned briefly that a knighthood might prove an unnecessary weight on his shoulders, after being informed by wife Kim via an email of the honour.

Murray, who was at a training camp in Miami at the time, told the Times: "I got it when I woke up in the morning, just saying that I had been offered and (asking) would I like to accept.

"I spoke to a few of the people closest to me. I didn't have too long but, obviously, you think about something like that because I do feel like it's obviously a big honour but, with that, comes maybe a little bit more responsibility.

"I'm still very young, I'm still competing and obviously don't want anything to distract me or affect my performance on the court."

Murray accepted the knighthood after discussing the issue with Kim and mother Judy - although brother Jamie was not confided in and only found out on the night of the announcement.

"I kept it fairly quiet and just spoke to the people that I was closest with and explained what the situation was. I just tried to get the best advice possible."

But the honour is already proving mildly awkward for Murray, who added: "A few of the players have been chatting to me about it and asking how it works, what does it mean and what do we call you. 'Andy is fine'."

In a wide-ranging interview, Murray revealed he would like to explore coaching once he quit tennis - and had not ruled out an audacious move into football.

"Something within British tennis probably, potentially coaching another player. I would like to do something in football. I watch loads of it. I am into my fantasy sports a lot.

"I would like to try my hand at coaching at some stage but I wouldn't think immediately after I finish. I would like to spend a lot of time at home with family and see my child, or children, growing up."
