The 26-year old Swedish full-back has emerged as a key player in the Hoops line-up since joining from Rosenborg in 2011 and says he is looking to stay put in Glasgow for the foreseeable future.
"I have two more years here then we'll see what happens," said Sweden international. "I'm happy, though, and I like Celtic as a club and Glasgow as a city.
"Celtic are bigger than I thought they'd be when I signed. You see how much it means to the people when you come here.
"I came from a small club in Scandinavia in comparison, where things didn't always work out the way you want as a player.
"But here we have people for everything at Celtic. It's a really big club."
