He is far more at home on the courts where he knows his talent will see him though.

And now Sir Andy Murray has revealed he finds having to act in TV adverts much tougher than tennis.

The 38-year-old has appeared in a number of commercials for firms since retiring from the sport.

He is a brand ambassador for a number of products including Walker’s Shortbread, Albert Bartlett potatoes, pet food firm Purina and footwear company Hylo.

However, he has revealed he feels uncomfortable having to act in front of the camera.

In the Hylo advert, which was released last month, the three-time Grand Slam champion appears in a parody press conference in which the microphones fail to work and the stage falls apart.

Murray is asked if he is looking to rival former nemesis Roger Federer - who has helped Swiss footwear brand On achieve a market valuation of £15 billion.

He denies there being any competition, before he shares a villainous grin into the camera to hint that he is eager to cut into Federer’s empire.

Asked about the experience of filming the advert, Murray said: ‘For me filming things like that is hard.

‘There is a lot of me trying to act - I don’t know if it is really acting or not but I was trying to.

‘There was a lot of people in the room and there was a lot of lines to remember and it’s difficult.’

In an interview on The Drop podcast, he added: ‘If you’re a professional athlete obviously you get nervous but there is a confidence in your ability to play tennis at the highest level.

‘Yes there are nerves and pressure that you have to perform but at least I knew I could do that to a high level.

‘Whereas where you’re being asked to act in front of other actors and extras it can be pretty awkward.

‘It’s a difficult thing. Acting is a lot harder than it looks so I find it very difficult.’

Murray retired from tennis after competing for Team GB at the Paris Olympics last summer following a glittering career.

He is also appearing on screens with his new puppy in an advertising campaign for dog food.
