West Ham have made a £20m bid for Marseille centre-back Duje Caleta-Car.
The 24-year-old Croatia international impressed in Ligue 1 last season under former Tottenham and Chelsea head coach Andre Villas-Boas
He joined Marseille from Salzburg in 2018 for £15m after being a member of the Croatia squad that finished runners-up at the World Cup in Russia.
West Ham’s bid for Caleta-Car comes after the signing of right-back Vladimir Coufa from Slavia Prague for £5m on a three-year contract on Friday.
West Ham also had a bid in the region of £13m turned down by Club Brugge for their captain Hans Vanaken.
