The Iceland forward, nicknamed 'Arnie', probably wasn't worth the £2 million dished out for his services from Bolton Wanderers in 1999. He was only a bit-part player for the club and most of his appearances were as 'super sub', scoring all his goals after coming on as a substitute.
He was a good luck charm for the Foxes in penalty shoot-outs, too, stepping up first to score in all of City's three penalty shoot-outs in the 1999-2000 campaign - living up to the Icelandic stereotype of being 'cool'.
Gunnlaugsson was a regular goalscorer for Iceland club Akranes, topping the domestic league scoring charts in both of his spells with the club, which surrounded a less successful stint with Dutch club Feyenoord. His move to England came via Bolton, but he failed to repeat his goal heroics of his time in his homeland in Lancashire and City quickly swooped to give him a chance for a return to form in front of goal.
He put in determined performances but often lacked that finishing touch, something which condemned him to the bench for long spells at Filbert Street. It forced him to move to Stoke City, where he turned a loan move in to a permanent one before having an unsuccessful stint north of the border with Dundee United. He returned to his homeland to finish his playing career.
