Career
Early career
Born in Reykjavík, Iceland, Hörður began his career within the youth academy of Knattspyrnufélagið Fram in 1998. He remained within the youth academy until 2010, although he managed to appear in 6 first–team matches between the 2009 and 2010 campaigns, with his debut coming in a 3–1 away defeat to KR on 30 August 2009. He remained with his local team until 2011, when he was transferred to Italian and European giants, Juventus.
Juventus
On 23 July 2011, Hörður officially transferred to Juventus F.C. where he was registered with the club"s youth academy.
After spending the 2011-2012 and 2012-2013 seasons with the Primavera (under-20) team, Hörður was promoted to the first–team squad ahead of the 2013-2014 Serie A campaign. Initially part of the club"s first–team training camp, Hörður was soon transferred to Serie B side Spezia Calcio on a co-ownership agreement completed on 5 August 2014.
He finished the season having made 20 league appearances for the side who finished in the final promotion play-off spot, although they failed to progress beyond the first post-season match following a 1–0 defeat away to Modena. In June 2014 Juventus bought back the 50% share of the player"s contract that they had sold to Spezia one year earlier, and immediately loaned Hörður out to Serie A outfit A.C. (before Christ) Cesena on 23 July 2014.
