Here’s how Twitter reacted to Van Gaal’s theatrics…
Huge win for United

With today’s result, Manchester United have boosted their chances of securing a top-four finish.
Van Gaal’s side now sit three points behind fourth-placed Manchester City, who were in Capital One Cup final action against Liverpool on Sunday afternoon.
Bad defeat for Arsenal
Arsenal, meanwhile, stay five points behind league-leaders Leicester City in third position.
Tottenham, though, extended their lead above Arsenal to three points with a 2-1 win over Swansea City.
