It's difficult to know how successful Louis van Gaal has been in his first six months as Manchester United manager.
On one hand, he's third in the Premier League table and into the quarter-finals of the FA Cup. On the other, there are supporters who have been underwhelmed with his style of football. That United have scored 12 fewer goals than leaders Chelsea so far this season.
Van Gaal's United have been functional. They've found a way to win games when they perhaps shouldn't have. It's a good quality to have, but not something to rely on in the long-term.
