Landon Donovan says he wishes he could continue playing football after his final game saw LA Galaxy triumph over New England Revolution.
The forward, 32, who has scored 57 times in 157 caps for the United States national team, featured in Galaxy's 2-1 MLS Cup victory.
He was already the most decorated player in the league's history and now has six MLS Cup championships.
Donovan said: "I don't want it to end right now. It's been a lot of fun."
The forward began his professional career in 1999 with Bayer Leverkusen in Germany, before going on loan to San Jose Earthquakes. He joined LA Galaxy in 2005 and has made 247 appearances, scoring 112 goals.
Donovan has spent time on loan at Bayern Munich and Everton - and played in three World Cups, though was left out of the 2014 squad by US coach Jurgen Klinsmann.

After the victory over New England, former LA Galaxy player David Beckham wrote on Facebook: "Great to see my old team LA Galaxy win MLS Cup. Robbie delivers again. Nice to see Landon win the trophy in his final game. Well deserved."
Team-mate Robbie Keane told the MLS website it had been "an absolute honour to play with him".
The 2-1 win came after a tactical change at half-time which, according to the LA Galaxy manager Bruce Arena, was orchestrated by winning goal-scorer Keane.
Striker Gyasi Zardes was pushed into a wide role, allowing Donovan to push up through the midfield behind Keane.
