Newcastle United have rejected a £25million bid for Jamaal Lascelles, according to a report.
Sky Sports claim that West Ham United bid for the club's captain.
The offer was reportedly an initial £20million, with an extra £5million in add-ons.
It is reported that Lascelles, signed from Nottingham Forest four years ago, is "not for sale".
The 24-year-old led Newcastle to a 10th-placed finish in the Premier League last season.
Lascelles addressed speculation over his future in May.
He told the Gazette: "This is the happiest I’ve been. I’m playing week in, week out. I’m the captain here. The fans love me. I’ve got a good relationship with them, because I love them."
