Niemi happy at Hearts
The Finnish goalkeeper has attracted interest from Charlton, but he seems confident about extending his stay at Tynecastle.
He said: "The only concrete offer for me was from Charlton so it has been really easy for me to concentrate on playing for Hearts.
"I still have one-and-a-half years of my contract to run and my agent is going to have a meeting with Chris Robinson later this month. Hopefully we will sort something out then.
"When you get older there are a lot of things you have to think about. My family is here, they like it here and I am more than happy."
The keeper is a key figure in manager Craig Levein`s plans, and he will be buoyed by the news that Niemi wants to stay in Edinburgh.
