Sweden coach Erik Hamren has refused to discuss his future following the team's failure to qualify for the 2014 World Cup.

The Swedes slumped to a 4-2 aggregate defeat in their playoff tie against Portugal on Tuesday as they lost 3-2 in Stockholm.

Hamren's current contract is due to expire at the end of the year, but the 56-year-old is unsure whether it will be extended.

"Today it's too early to talk about [my future], I'm just too disappointed," he told Reuters.

"I just want to go to bed and stay there. But we'll have that discussion in a short while. It's a fantastic job, but we'll see."

Hamren took charge of the Swedish national team in 2009.
