Athletic Bilbao in 2007 Iraola was born in
Usurbil,
Gipuzkoa. He played as a youth for
Antiguoko, alongside teammates such as
Mikel Arteta,
Xabi Alonso,
Mikel Alonso and
Aritz Aduriz. A product of
Athletic Bilbao's youth system at
Lezama, he made his debut with the first team in the
2003–04 season, becoming first-choice while often taking
penalties and
free kicks. On 30 August 2003, he made his first
La Liga appearance, starting in a 1–0 home loss against
Barcelona, and his five goals in 30 appearances helped the team to
qualify for the
UEFA Cup.– while also helping the
Basque side to finish second in three
Copa del Rey tournaments and the
2011–12 UEFA Europa League. On 28 January 2007, he netted twice in a 2–0 away win over neighbours
Real Sociedad, who were
finally relegated; Athletic narrowly avoided the drop, ranking in 17th position. He played his first cup final
in 2009, a 4–1 loss to Barcelona at the
Mestalla Stadium in
Valencia, and three years later helped them to finish runners-up in both
the domestic cup and
the Europa League.
2012–13 marked the first year where Iraola failed to find the net in the league, but he continued to be the side's first-choice in his position as he featured in 35 games. His only goal of the season came on 24 August 2012 in a 6–0 home rout of
HJK in the
playoff round of the
UEFA Europa League (9–3 on aggregate). Iraola renewed his contract with the club on 4 December 2013, keeping him at the
San Mamés until 30 June 2015. In the 24th minute of his last league appearance against
Villarreal in May 2015,
Aritz Aduriz offered him the taking of a
penalty kick but he declined, so the former converted it instead; the two players then combined for Iraola to score from open play four minutes later. He
captained the team in his last match, the
2015 Copa del Rey final which was lost 3–1 to Barcelona.
New York City FC On 16 June 2015, aged 33, Iraola moved abroad for the first time in his career, signing for
Major League Soccer club

Toronto FC at the
Yankee Stadium on 12 July, playing the entirety of a 4–4 draw. Iraola announced his retirement on 17 November 2016. ==International career==
