Jaaskelainen happy to stay with West Ham
An option of a further year with the Hammers is set to be activated.
"When I first came here I signed a contract that if we stay up I would stay on so there's nothing to sign," the former Bolton goalkeeper said.
"I'm happy but we're obviously not over there yet - staying up. So I don't really have to do anything about it apart form make sure we stay up.
"It was always going to be difficult when you've had 14-and-a-half years at one football club and you're wondering what's going to happen but I've really enjoyed it.
"Big Sam was the reason why I wanted to come here.
"When he gave me the phone call straight away I thought it would be fantastic to play with him again because I know what kind of stuff he does with his players."
