Sir Andy Murray has said he became so addicted to video games that it was affecting his performance on court.

The tennis star admitted he was obsessed with gaming and would stay up until the early hours of the morning playing before big matches.

The three-time Grand Slam winner never travelled without his Playstation when going to tournaments around the world.

However, he said the late-night sessions of games like Pro Evolution Soccer left him feeling tired when he took to the court hours later.

The 32-year-old said he gave up gaming while at big events a few years ago just before the most successful period in his career.

He said: "I would travel with a Playstation everywhere until probably I was like 26.

"I was playing way too much.

"I had to play tennis the next day and I was playing until like 2 or 3am. It would be hours, not minutes.

"Pro Evolution Soccer is what I used to play."

Murray's former coach Brad Gilbert said the Scot played video games for seven hours a day when they working together in 2006 and 2007.

The American said the player's "obsession" with the games caused rows between the pair.
