Who is RoShaun Williams? Speedy defender included Manchester United debut against West Ham in FA Cup

The 17-year-old broke school sprint record back in 2014

Manchester United manager Louis van Gaal could give a debut to yet another youngster this afternoon, when United host West Ham in the FA Cup sixth-round.

The 17-year-old RoShaun Williams has been included in the squad.

The centre-back was born in Manchester, and joined the club last summer.

The rapid Williams made the headlines in 2014, when he broke Darren Campbell's 100m record at his school in Manchester by running a time of 10.99sec.

Despite coming in for much criticism for his tenure, with United languishing in sixth place, there have been positives with Van Gaal's youth policy.

Before today's match, the Dutchman had given 14 United graduates from their academy a chance, including first-choice winger Jesse Lingard and striker Marcus Rashford.

The match today at Old Trafford kicks off at 4pm, with the winner heading to Wembley Stadium for the FA Cup semi-final. United have not won a trophy since Sir Alex Ferguson stepped down as manager in 2013.
