Koikili Lertxundi

On his 27th birthday, he scored his first top-flight goal in a 1–1 home draw against Real Murcia.

Koikili Lertxundi del Campo (born 23 December 1980), known simply as Koikili or Koi for short, is a Spanish former professional footballer who played as a left-back.

A late bloomer, he only became a professional at the age of 26 after signing with Athletic Bilbao.

Over a five-year spell with the club, he appeared in 98 competitive matches.

Koikili was born in Otxandio, Basque Country.

He made his La Liga debut on 26 August, playing the full 90 minutes in a 0–0 home draw against Navarrese neighbours CA Osasuna, whose reserves he had already represented in the late 90s/early 2000s.

Koikili was first choice for much of the campaign, dislodging international Asier del Horno.

Playing Tercera División football just two seasons before moving to Athletic Bilbao, he was signed from Segunda División B side Sestao River Club for the start of 2007–08.

Koi appeared slightly less in the following two seasons for Athletic, but still totalled 52 official games (ten in the Copa Del Rey, with the team reaching the final in the 2008–09 edition, and one in the newly created UEFA Europa League).

On 11 January 2009, he netted the 1–1 at Atlético Madrid in an eventual 3–2 win.

Koikili was deemed surplus to requirements at Athletic in 2011–12 after the appointment of manager Marcelo Bielsa, alongside teammates Aitor Ocio and Iban Zubiaurre – he remained with the club, however.

On 25 June 2014, he retired at age 33 after spending two Segunda División seasons at CD Mirandés.

Koikili was a Greco-Roman wrestler in his youth, once being crowned Spanish champion at under-15 level.
