Stephen Hendry has admitted he longer enjoys playing snooker.



Seven-time World Champion Hendry believes he may have played his last match after he fell to a 13-4 defeat against Mark Selby in the last 16 of the Betfred.com World Snooker Championship.



"In the first two sessions I was taken apart and Mark was awesome - every time he got in I just put my cue to the side as he never looked like missing," said Hendry.



"I will decide my future in the summer and I'm not going to decide straight away.



"I still have the game but I don't have the self-belief to compete with these guys.



"If you're not truly believing you're going to win then you're going to struggle. Without wins it doesn't change but you need wins to get some self-belief.



"I love playing in the Crucible arena but it's hard to be competitive when you're coming down not believing you can win the tournament. If I can't win, or believe I can win, then I'm not going to enjoy it."



Selby claimed a record during the match by becoming the first man to make six century breaks in a match at the Crucible.



He led 7-1 after the first session and 12-4 after the second, before wrapping up the victory in 12 minutes of the third session.



Selby admitted Hendry was one of his sporting heroes and hoped the 42-year-old Scot would not retire.



"Stephen has been great for the sport and I wouldn't like to see him retire," said Selby.



"When he was in the balls he still looked as good as ever. I've played him a few times over the last couple of years and that's been the best he's looked.



"He's the one who set the standard so high and I've dominated in one game but he did it for years.



"In my eyes he's the greatest player to have played the game. When he was at his peak his belief was always higher than anyone's but now he is losing to players he probably thinks he shouldn't do.



"When you played him before when he got in the balls you thought it was frame over but now you think 'I might have a chance'.



"The standard of snooker he is playing is not as good as he used to and that must be hard for him.



"I used to love watching Jimmy White but as far as idols go the player I looked up to was definitely Stephen."



Hendry is on the verge of falling out of the world top 16 for the first time in 23 years and will do so if Stuart Bingham, who leads 9-7, beats Ding Junhui on Monday evening.



A refusal to play in many of the Players Tour Championship events has hurt Hendry's ranking and he revealed he has to decide whether he has a playing future.



"I'm glad I never got beat a session early and that was my one aim yesterday," added Hendry.



"If Stuart beats Ding then I'm out of the 16 and that will have a big influence on what happens.



"But if someone says you will have 26 years here and win seven world titles then you would have taken it.



"I've won the World Championship seven times, which is a record, and snooker is all I've known. I will still be involved in the game and I have one or two things in the pipeline.



"If I'm not playing, I will still be involved in snooker but I've not a bad time. I was not a bad player."
