The day is coming when Clint Dempsey will no longer be a professional soccer player.
Exactly when it will arrive isn't known yet. But this year is the first of the 34-year-old's 13-season career when that time has been visible on the horizon.
Dempsey isn't a guaranteed 90-minute player anymore for the U.S. national team, as a new era of young attacking prospects begins to make its mark.
The Seattle Sounders have been on notice since last August, when an irregular heartbeat sidelined Dempsey for the rest of the calendar year.
But that tough, spunky kid who learned the world's game on fields in the small east Texas town of Nagodoches is still going. And he still has the one skill that matters most.
If a big goal is needed, Dempsey is the man for the job.
"When his team is up against it, whether it's Seattle or the national team, and they need someone to make a play, Clint is as good at that as anyone our country has ever had," said Union manager Jim Curtin, who played against Dempsey in MLS in the early 2000s.
Four of Dempsey's 12 goals for Seattle this year have been game-winners or game-tiers. Two more extended one-goal leads to two.
In this year's national team World Cup qualifiers, he scored a hat trick at home against Honduras and the opener in a 1-1 tie at Panama.
In this summer's Gold Cup, he tied Landon Donovan's national team goals record with a free kick that sealed the semifinal win over Costa Rica.
Four days later, he helped Sounders teammate Jordan Morris score the title-winner in the game's final minutes.
Things haven't been as rosy since then. The Americans must beat Panama in Orlando next Friday and Trinidad & Tobago on the road the following Tuesday to qualify for next year's World Cup.
But would anyone really be surprised if Dempsey scores the goal that saves the ship and books the ticket to Russia?
Just ask Union captain Alejandro Bedoya, a longtime friend of Dempsey's. Though it isn't official yet, the two of them are likely to head to Orlando after Sunday's game at Talen Energy Stadium (1 p.m., ESPN).
"The way he carries himself as a person on and off the field, he has this never-back-down personality about him that makes him so strong mentally and physically," Bedoya said. "He's always striving to be better, and is always up for any challenge."
The same Union fans who boo Dempsey's name Sunday will cheer it a few days later, as they have done so many times over the years. It is a strange juxtaposition, but it is the essential nature of soccer. The world's game weaves together professional and national team allegiances like no other sport in the American tapestry.
He has only played one game here for the Sounders, but it was a big one: the 2014 U.S. Open Cup final. He scored the game-winning goal.
It's hard to know yet whether Sunday's game will be his last appearance here. His national team career is likely to end next year; his club career could go on. This much is certain: the Sounders won't be back here until 2019. So it's worth appreciating Dempsey's legacy while he's in town.

Midfielder Cristian Roldan: He brings passing vision and a big engine to the center of the Sounders' midfield. The 22-year-old cracked the U.S. national team at the Gold Cup this summer, and has the potential to stay there for a while.
Defender Román Torres: If you've ever wondered what a football player would look like playing soccer, watch this beast of a centerback. He got his star turn at last year's MLS Cup final, shutting down Toronto's big attacking guns and scoring the title-winning penalty. You'll likely also see him playing for Panama's national team against the United States next week.
