Before last night's 1-0 victory over CSKA Moscow in the Champions League, United had failed to score against Manchester City, Middlesbrough and Crystal Palace.
And Red Devils legend Scholes, who previously hit out at Van Gaal's "boring" style of play, was quick to criticise again, claiming City forward Sergio Aguero would find it difficult in his side.
"I want United to blast teams away and be creative. I want to see that but it’s not happened," he told BT Sport.
"I think they’re brilliantly coached defensively. Sometimes you’ve got to do that against Barcelona or Real Madrid but not against Crystal Palace or CSKA Moscow at home.

Scholes believes United have abandoned their attacking traditions
"It’s difficult to coach attractive football. Whether Van Gaal doesn’t allows it, I don’t know. It’s a boring style of football.
"You have to wonder whether he has problem with forward players. Just look at the players he’s let go - Van Persie, Januzaj, Di Maria.
"Look at the bench on Saturday, there wasn’t a centre forward.
"Rooney is getting all the stick but think any striker would struggle to score goals in that team. I think Sergio Aguero would struggle."
