The Swedish international midfielder, whose current contract expires next summer, had been in talks about a new five year deal with Blues' previous owners but they had to be put on hold whilst Carson Yeung's takeover at St Andrews was completed.
“All I have said all along is that it’s up to the club now to let me know what they want to do, then we will see what happens,” Larsson told the Birmingham Mail.
“If we can agree on something then I am more than happy to sign a new deal. But it’s one thing just saying it, you need to start talking and agree something.
“I’m not worried about it. There is a lot of new stuff I suppose for the owners and the board to deal with, we will see.”
“With the old board there was a contract offer a while ago which was never signed (after relegation) and then there was not much happening until the end, when they left, and it was put on hold.
“Now there are new owners and we will have to wait and see what they want to do.
“Progress had been made, yes. We weren’t 100 per cent there, but we were close to each other than we were before.”
