Manchester United’s interest in Dutch midfielder Kevin Strootman has taken a back step after Roma director of football Walter Sabatini re-affirmed that he was not for sale. Man United’s interest in Kevin Strootman first took a step forward when Louis van Gaal was first mentioned as the long term replacement for David Moyes and pictures of both along with Robin van Persie quickly gave United hope. The former PSV Eindhoven midfielder has struggled for form this season due to injury troubles but new United boss Van Gaal is a big admirer and had indicated the 24-year-old as the perfect summer signing. However, his chase has been halted by Roma’s director of football, Walter Sabatini, who has been quick to re-affirm that the midfielder will be staying in Rome. Strootman joined Roma last summer in a 17m deal and is expected to play a key part in the Italian capital side’s Serie A title challenge next season. The midfielder will not be at the World Cup this summer after a knee injury ruled him out.
