The midfielder struck in victory over Chelsea yesterday.
He told The Sun: : "I want to give all to this club for a long time. It's quite strange because all my career I've been with clubs for two or three years.
"Normally I change clubs after one or two years but it's different here. I want to stay longer.
"Sometimes you're not happy with something or you don't feel comfortable in the city and you need change - but not here.
"Of course I'd like to end my career here. For three years it has been enjoyable to be with guys who love you, guys who care about you."
