Aymeric Laporte has signed a new four-year contract with Athletic Bilbao that significantly increases his release clause.
The 22-year-old centre-back is now under contract with Athletic until June 2020, with his fresh deal including a buy-out fee of €65 million for the first two years of the deal, rising to €70m in 2018.
Laporte's previous deal had only been signed in June 2015 and was due to expire in 2019, with a release clause of €50m.
The new agreement should bring an end to reports linking the centre-back with Barcelona and Manchester City.
