Igor Arnáez Martín (born 30 April 1991) is a Spanish former professional footballer who played as a left-back.
Born in Bilbao, Biscay, Basque Country, Arnáez graduated with Danok Bat CF's youth setup, after a short stint with Athletic Bilbao. He made his debuts as a senior with SD Lemona in the 2010–11 campaign, in Segunda División B.
In July 2011 Arnáez returned to Athletic, being assigned to the reserves also in the third level.[1] However, after appearing sparingly, he was loaned to fellow league teams Sestao River Club[2] and SD Amorebieta,[3] respectively.
On 26 May 2014 Arnáez was released by the Lions,[4] and moved to Segunda División's CD Tenerife on 27 August.[5] He played his first match as a professional on 9 September, starting and playing the full 90 minutes in a 0–0 away draw against Girona FC for the season's Copa del Rey.[6]
