“I’ve just verbally agreed a two-year contract, maybe extending to three,” Keane told Sky Sports News.
“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.
“As soon as you hit that 30 age mark in football, people are reluctant to give you contracts but this will be the third contract I’ve signed since I’ve been there and it shows the faith they have in me.”
Keane has been a brilliant signing for MLS, scoring 34 goals in 49 appearances on the way to helping the Galaxy win back-to-back MLS Cups.
The 33-year-old Keane also defended the quality of the MLS to Sky, saying that if overseas stars are looking for an easy option at the back end of their careers then MLS is not for them.
“Since I’ve been there, it’s been a strong league,” he added. “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.
“When people come over to play in it, I always tell them, ‘don’t think you’re coming over for a holiday’. There’s a lot of pressure on the three designated players [non-American contracted stars] as people are expecting you to deliver all the time.”
