Milan transfer target Eduardo Quaresma is expected to sign a new contract with Sporting CP, including a €45m release clause.
The Rossoneri were repeatedly linked with the 18-year-old centre-back, whose current deal runs to June 2021.
According to A Bola in Portugal, Quaresma has now agreed personal terms for a new contract tying him to Sporting until June 2025.
This will include a release clause worth a massive €45m for the teenager.
He is still only in the Under-23 team and played 23 games in the Liga Revelacao this season.
