Andy Murray burst into tears as he won his first ATP Final title since March 2017.
The Scot struggled with hip surgery and a series of setbacks to prove glory once again.
He beat Stan Wawrinka 3-6, 6-4, 6-4 and won the tournament in Antwerp in a memorable week of action.
His wife is back home and is currently expecting her third child.
"I didn't expect to be in this position, so I feel very lucky," Murray said excitedly, speaking to Amazon Prime Video.
"It means a lot. The last few years have been extremely difficult.
"I didn't expect to be in this position. I'm happy, very happy."
Murray nearly quit the sport earlier this year when he announced that the Australian Open could be his last major title.
Wawrinka also revealed his joy as most tennis fans saw Murray return to the top of his game.
"Seeing you back to this level is amazing," said the Swiss.
"We are all very happy. I am sad to have missed you today, but I am very happy to see you back."
He was planning to play at Wimbledon before ending his career, but lost it and continued to move on.
"I did everything I could to try to improve my hip and it didn't help much," Murray said in January.
"I'm in a better place than six months ago, but I still feel a lot of pain. It's been hard.
Murray was defeated in the first round in Melbourne earlier this year, with his career hanging by a thread.
He added before the tournament: "During my training block, I talked to my team and told them I couldn't keep doing that. I needed to have a period, because I was kind of playing with no idea when the pain would stop. .
"I said to my team: Look, I think I can get this over to Wimbledon. That's where I'd like to stop playing. But I'm not sure if I can do that either."
