Timothy Fosu-Mensah has agreed a new long-term deal to stay at Manchester United, according to British newspaper reports.
The Daily Telegraph claims he will sign a new four-year contract with the Daily Mail adding an official announcement will take place in the coming days.
The 18-year-old defender, who joined United's academy squad from Ajax in September 2014, made his first-team debut in the 3-2 win over Arsenal in February.
He made 10 appearances for the first team last season, which included a start in the FA Cup semifinal win over Everton.
By signing an extension Fosu-Mensah would join 18-year-old Marcus Rashford and 19-year-old Cameron Borthwick-Jackson as young players who have been rewarded with new deals since Jose Mourinho became United manager.
However, Paddy McNair and Donald Love, both 21, have left for Sunderland.
Fosu-Mensah faces competition for a place in the side as right-back, with Antonio Valencia having been impressive in preseason and Matteo Darmian a second senior option.
