A fifth-place Premier League finish means the Europa League now awaits Manchester United, but Wayne Rooney has no complaints after a difficult campaign in which they netted a meagre 49 goals - the club's worst return for 26 years.
"We haven't scored enough goals this season," he said. "In the Premier League after 38 games, you finish where you deserve to finish.
"There's no complaints from us as players. We weren't good enough to finish in the top four this season and we need to improve on that next season."
It has been a frustrating season - one which could well cost Van Gaal his job - yet they can still end it with silverware.
Saturday's FA Cup final against Crystal Palace could see United lift their first major trophy since Alex Ferguson retired, with Rooney hoping Tuesday's win acts as a decent platform.
"It was obviously a difficult game in terms of what happened on Sunday, and we knew that fourth place was gone for us," he said.
"We had to make sure that we went out and that we didn't let that affect us because we've got a big game coming up on Saturday and we wanted to stay in good habits for that game on Saturday."
