PSV Eindhoven defender Jetro Willems has been ruled out for the remainder of the season and the World Cup with a serious knee injury. Willems became the latest blow to Holland coach Louis van Gaal’s plans ahead of this summer’s World Cup, after Kevin Strootman was ruled out of the tournament in Brazil last month through injury, after picking up a knee injury in a 2-0 defeat to Feyenoord. The 20-year-old was forced off early with the injury and a statement on PSV’s official website revealed that Willems has damaged “the inner tube of his knee”, ruling him out for “several months”. Willems, who has been linked with a move to Manchester United, suffered the injury in front of Holland boss Van Gaal, who is reportedly holding off committing himself to Tottenham to wait and see what happens in regards to David Moyes’ position at Old Trafford, who watched sat alongside Strootman and Robin van Persie. “Jetro Willems is no longer in action for PSV this season,” the statement read. “The left-back has damage to the inner tube of his knee and is therefore out for several months.“Willems now focuses on preparing for the new season.”Read more Manchester United transfer news.
