West Ham have had an offer for Harry Maguire accepted by Manchester United.
The Irons had a previous bid of 30m turned down by United, but has since returned with an improved offer.
The new proposal is for similar upfront with add-on bonuses.
BBC Sport says Maguire is keen on the move and ready to enter talks over personal terms with the Irons.
Maguire joined United in August 2019 for a world record 80m for a defender.
He made only eight starts for United last season.
