West Ham United have reportedly placed an £18m price tag on the head of Reece Oxford.
The 17-year-old, who made his Premier League debut on the opening weekend of the 2015-16 campaign, has been strongly linked with both Manchester United and Manchester City this summer.
Newly-promoted Bundesliga club Red Bull Leipzig are also believed to have made a £10m offer for the England youngster, which was rejected by West Ham co-chairman David Sullivan.
According to the Daily Mail, West Ham are open to selling the highly-rated centre-back, but interested clubs will have to meet the Hammers' asking price of £18m for a player that has only made 12 senior appearances.
It is understood that Oxford is currently not prepared to sign a new contract at the Olympic Stadium.
