London: Ronnie O`Sullivan joked "I feel like retiring" after edging Judd Trump 10-9 in a nail-biting final to claim his fifth UK Championship title.
O`Sullivan led 9-4 at one stage of Sunday`s contest at York`s Barbican Centre, only for Trump to reel off five frames in succession, taking the match to a deciding frame.
But O`Sullivan, who broke his ankle while jogging shortly before the tournament, produced a break of 51 to claim victory.
"I can`t believe I`ve won it. I don`t want to be playing him in every final. I feel like retiring," said the 39-year-old, who has also won five World Championships and five Masters titles.
"He`s a tough opponent, he`s very dynamic and very explosive. He`s fearless, and he`s in your face the whole time, and if you go off the boil, he`s on you.
"I`m trying to make the most of however long this lasts. I`m going to enjoy this moment. I`ve won the Champion of Champions title and now the UK Championship.
"I`m delighted to have had a great few weeks and I can start to think about defending the Masters in January."
Victory crowned a glorious year for O`Sullivan, with the only dark spot being a loss to Mark Selby in the World Championship final in May.
His triumph against Trump earned him £150,000 ($234,000) in prize money, to go with the £44,000 he was awarded for a 147 break against Matt Selt earlier in the tournament.
Trump, 25, said: "I left it too late and fair play to Ronnie -- he took them well in the last frame and overall he was more of a deserving winner."
