Inaki Williams has put pen to paper on a mammoth seven-and-a-half-year contract extension with Atheltic Club.
The 23-year-old winger was previously linked with a switch to Liverpool but has committed his long-term future to the Basque club, where he is now tied until 2025.
Williams' new contract includes a release clause of €80 million that will progressively rise until it reaches €108m, figures which exceed the fee required to take star centre-back Aymeric Laporte away from Athletic.
The news will come a boost to fans with goalkeeper Kepa, whose deal expires at the end of the season, heavily linked with a move to Real Madrid.
Williams has featured in all 19 of the club's outings in La Liga this season, contributing four goals and three assists.
