Colin Montgomerie has admitted he could be tempted to end his Ryder Cup playing career in order to take on the captaincy of the team in 2006.
The Scot holed the winning putt in Europe's victory at Oakland Hills.
But he said: "There is a time in life to go out and most people tend to delay that decision a little bit too long.
"I don't know whether that was it on Sunday. I have to come to a decision - am I worth more points to the team cause as a captain or a player?"
At a news conference after the team landed at London's Heathrow airport, Montgomerie said he would play on if he felt he could continue his strong form in the tournament.
"If I can perform the way I did this year, if I can help the team in some way, I'd like to play. But that's a decision for whoever picks the next team."
This year's captain Bernhard Langer hinted that he would probably not take on the job again.
Ian Woosnam, who was deputy to Sam Torrance in Europe's 2004 win, Nick Faldo and Sandy Lyle have all expressed their interest in the captaincy.
Montgomerie, who had to rely on a wildcard place in the team after his indifferent form this year, said he felt the format of the tournament suited him.
"I like the fact that if I mess up there are 11 guys who can make up for it," the Scot said.
Montgomerie admitted his team-mates had been urging him to play on, but having relied on a wildcard to make the team this time, the Scot felt he would have to qualify by right for the 2006 team.
"They want me to play but I've got to play my way onto the team again. I can't expect to get picked again," he said.
"They all know how much I enjoy this and if I can be relied upon I'd like to play but if not I'd like to go into another role.
"There is a time to get out. I always said I want to get out as close to the top as I can be.
"And I've got to make a decision, not about not playing golf, but in this type of format whether I'm going to add to it or add to it in a different way.
"I would love to help the team cause in any way, shape or form."
Montgomerie, who travelled to Detroit just three days after confirmation of his divorce from his wife, paid tribute to his team-mates for their support.
"It's not easy, I was on my own here," he said.
"Lee Westwood was also on his own because his wife had just given birth and he was great with me.
"A number of people have come up to me and been through this situation and understand, it's amazing the support I've been given but no more so than this
"I was more emotional when Bernhard told me I was in the team. I was trying to do a job for the team so I couldn't let it affect me, I could let it affect me when Bernhard told me I was in the team.
"I was emotional then because I wanted to be here and I didn't get anywhere near qualification for this team."
