Madrid (AFP) – Young French centre-back Aymeric Laporte extended his contract with Athletic Bilbao on Monday despite reported interest from Manchester City.

The 22-year-old added a year to his existing deal and is now tied to the Basque club until June 2020, Bilbao said in a statement on Monday.

The France under-21 captain is rumoured to be a target for new City manager Pep Guardiola.

His new deal includes an increase in his buy-out clause from 50 million euros ($56.5 million) to 65 million euros, rising to 70 million euros in two years time.

Laporte was born in Agen in the Aquitaine region of France but has Basque grandparents.

Last year he said he would consider representing Spain if he wasn’t called up by France coach Didier Deschamps for Euro 2016.

He made his debut for Bilbao, his only professional club, in 2012.
