Wolverhampton Wanderers are eyeing up Lazio defender Bastos and the asking price is €15m.
The 27-year-old Angola international has been at the club since 2016, when he completed a €5m transfer from Rostov in Russia.
He is under contract until June 2020, with the option to add another year, but has struggled for playing time.
According to Il Messaggero newspaper, Bastos is a transfer target for Premier League side Wolves.
Lazio have reportedly set the price-tag at €15m for the tall centre-back, who scored five goals in 28 competitive appearances last season.
