Louis van Gaal’s best quality is to create a team and to get a squad playing brilliant football

But former United goalkeeper Van der Sar feels Van Gaal will be able to transform the Red Devils’s fortunes without a marquee summer signing.
“Louis van Gaal’s best quality is to create a team and to get a squad playing brilliant football,” Van der Sar told the Mirror.
“Over the last few weeks, the United fans have witnessed how he guided this young, inexperienced Dutch squad to the semi-finals – a squad which nobody gave a chance to finish in the top eight.
“Louis will arrive at Old Trafford with a glowing CV, based on the things he has done in European club football and on this World Cup in Brazil.”
Van Gaal signed a three-year deal to become the next United manager in May.
