The 28-year-old did not feature regularly at the start of the last campaign under newly-installed boss Brendan Rodgers, prompting speculation that he may be sold.
"I'm here to stay," he told the Liverpool website. "I'm enjoying it, especially last season when I got a good run in the team. Hopefully that will continue, and I need to work hard.
"I want it to continue. It's why I came here, to play in a successful team."
