The Irishman looks set to end his career with the Galaxy, after announcing he'd agreed to stay on for at least another two seasons.
Speaking to Sky Sports, the 33-year-old said: "I've just verbally agreed a two year contract, maybe extending to three.
"I'm certainly excited about that and playing for the Galaxy in the future. I didn't think I was going to go there and then come back to the Premier League, but I'm enjoying my football there and the club has been very good to me."
Keane is coming off a season where he had 16 goals and 11 assists in 23 appearances with the Galaxy, who were eliminated from the playoffs by Real Salt Lake in last week's Western Conference semifinal.
"Since I've been there it's been a strong league," Keane said. "It's a tough league because of the structure that works there with everyone competing at roughly the same level. Every team can beat every other so it's very competitive."
The striker joined the Galaxy from Tottenham in 2011, and helped his team win back-to-back MLS Cups in 2011 and 2012 before LA's bid for a third consecutive title was derailed this season.
