Usman Khawaja says he never doubted his own ability after scoring 137 runs as Australia declared at 8-416 on the second day of the fourth Test at the SCG.
The Aussies are priced at 15/8 to win the Ashes 5-0 and have given themselves a chance after taking a grip on the fourth Test on Thursday.
England survived the last five overs of the day to finish on 0-13 but it was the performance of Khawaja that will make the headlines.
The 35-year-old returned to the Test arena after a three-year absence to fill in for Travis Head and he grabbed the chance with both hands, giving the selectors a huge headache in the process.
Travis Head looks sure to return after impressing in the Ashes before having to sit out at the SCG but Khawaja will now be hard to leave out in the fifth Test.
Youngster Cameron Green's place is under threat, while Marcus Harris will also be anxious if Khawaja is pushed up the order to open the batting with David Warner.
Those are decisions to be made down the line but Khawaja seems relaxed whatever the outcome as he is just delighted to be out there playing cricket and enjoying life.
"It's pretty sweet moment. I wasn't expecting it. Hundreds don't come every day and it's a pretty tough wicket. I was just trying to bat, and grind away. It was a lot of fun. I am a bit lost of words and a little tired," Khawaja said at the end of play for the day.
"I didn't doubt my ability at 35. I've been in a good spot the past few years after I got dropped. My wife and family have been very supportive. I haven't got anything to prove, not to myself nor anyone else. I love playing cricket whether it's at my local club or Queensland. I'm just loving the game.
"Getting selected for Australia is a bonus for me. I am enjoying my life at the moment. I was so relieved when Pat got me back on strike at 99 - I didn't want to be stuck on that over tea!"
