Blind, 25, is well used to Van Gaal's methods from his time in charge of the Holland team and believes the players have subscribed to his belief.
He said: "He has his own philosophy and approach which players have to adapt to.
"In the end you see that it makes you better and it makes a better team. I think everybody has realised that now.
"It's important that we have stuck together as a team, even when it's not going so well."
