Roshaun Williams has been called up to the Manchester United squad to face West Ham on Sunday, Football Insider sources understand.

The 17-year-old defender has been promoted to the senior set-up, where he will join fellow teenager and Academy graduate Marcus Rashford, 18.

Adnan Januzaj has also been recalled after being cup-tied against Liverpool in midweek and being omitted from the squad against West Brom last weekend.

Williams becomes the latest in a long line of Academy graduates to be fast-tracked into the United team under Louis van Gaal.

The first-year academy scholar Williams has been selected for his maiden squad promotion despite the recent emergence of Timothy Fosu-Mensah.

Williams, who played alongside Januzaj for United Under-21s at Liverpool on Friday night, has been a mainstay of the development squad this season and was expected by many observers to have been promoted earlier to the senior squad.

Such is Williams’ precociousness he broke into the United Under-21s as an Under-15 squad member and made his Under-21 debut as a 16-year-old.

Williams arrived with the 18-man squad at The Lowry Hotel on Saturday night as Van Gaal’s team stepped up their preparations for Sunday’s FA Cup quarter-final clash against West Ham at Old Trafford.

Juan Mata is suspended for Sunday’s tie following his expulsion in last week’s defeat to West Brom.

Man United squad: De Gea, Romero, Darmian, Williams, Varela, Smalling, Blind, Rojo, Schneiderlin, Schweinsteiger, Fellaini, Carrick, Herrera, Depay, Januzaj, Lingard, Martial, Rashford
