Despite naming a strong line-up, Van Gaal's side failed to break down the League Two side and will now be forced into a replay at Old Trafford.
And the Dutchman believes a lot of things were going against his side including the referee.
"Every aspect of the match is against us," Van Gaal said after the game.
"We have to come here and the pitch is not so good. That can influence your playing style. The opponents are giving a lot more than normally and defending is always easier than attacking. Then you see the referee, it's always the same. Everywhere I have coached, it's always the same with this referee.
"I know it's very difficult to beat such an opponent in these circumstances. I know that in advance – I said it in my press conference before the Yeovil Town game. We know in advance everything is against us."
