Manchester United are ready to step up their interest in Dutch wonderkid Daley Sinkgraven. Louis van Gaal is worried that the Old Trafford giants may lose out on the 19-year-old attacking midfielder to Real Madrid, Barcelona or Liverpool after some eye-catching performances for Heerenveen this season. He has ordered his scouting team to bring him more detailed reports about Sinkgraven’s progress with a view to agreeing a deal with his Dutch club in January.
