Louis van Gaal has not managed to lift a single piece of silverware for Manchester United since his appointment as the head coach back in May of 2014.
In all fairness, the Dutchman had a difficult job to do when he was selected to succeed David Moyes and so far the team does get far better results than they used to with their former coach.
Even with all the progression that has been seen in the team, something which is non-existent is the trophies. The Dutchman still has not secured a piece of silverware despite having spent a substantially large amount of money in signing players and improving his squad.
To make matters worse, Manchester United was knocked out of the Champions League in a fairly disappointing way as they lost against Wolfsburg but now have the possibility of competing in the Europa League and start winning some titles.
