The Liverpool defender says he won't let his 94th minute own goal on Tuesday get him down and will come back stronger than ever.
"What can I say? I decided to stoop and head the ball in the direction it came from," said Riise.
"But it was a swerving cross, the ball was wet, and it slid right off my forehead. It was a shock to see it lying in the goal.
"These things happen for defenders from time to time. I know how strong I am mentally and I will handle this and I will come back from an own goal like that.
"I have been involved in tougher things in my life than this and I know that I will handle this in a good way. I will try to turn this around to something positive."
