Olsson penned a new four-year deal with the club in October, which came after a summer of speculation about his future.
The 30-year-old Swedish international insists he is happy at The Hawthorns, but he wants the club to continue to push on.
"You want to see the club on the front foot and progressing. I feel that at the moment. That's why I'm happy with my situation," he told the People.
"When you don't feel that, you look at your own position and where you're heading."
Olsson has been the subject of interest from QPR and West Ham in the past 12 months and he admits a move to London is still an ambition of his.
He added: "I love the mix of football and London and the feeling when you're down there. That's the ambition in the future."
