VIDEO: Sheffield United's job was 'easy' says Manchester United boss Louis Van Gaal

Manchester United boss Louis Van Gaal took a swipe at those giving credit to Sheffield United for their FA Cup performance at Old Trafford on Saturday by saying 'defending is easy'.

Van Gaal's team laboured against a resolute Blades outfit who remained disciplined in their approach, right up to injury time when Dean Hammond brought down Memphis Depay in the box and Wayne Rooney hammered home the resultant penalty for the only goal of the game.

Manchester United found it difficult to break down the League One side and many disillusioned home supporters had left the ground by the time England's record goalscorer had finally hit the net.

But the Dutchman said, referring to other performances by lower ranked teams in the FA Cup: "When you see the results today you see that every lower team is making a good result because defending is more easy than attacking and everybody knows that."

Van Gaal did recognise that his side didn't play well but concentrated on the fact that they will be in the hat for Monday's fourth round draw.

"You have to play more quickly than we did in the first half. They are defending with 10, 11 players behind the ball. It's more easy to defend than attack," Van Gaal said

"I can understand (why) the manager of Sheffield United choose this kind of tactics, but they didn't have any chances, we have kept another clean sheet and we deserved to win.

"Okay it's not good today. We did not move the ball quickly today. But we have won and that is the most important thing in the FA Cup - we have to be in the next round and we are there."

Old Trafford legend Paul Scholes attacked the current crop of Manchester United players for their performance and said he is relieved they have avoided having to go to Bramall Lane for a replay.

"I'd be depressed (after that game). It would take me two or three days to get over that performance," said Scholes, speaking as a pundit on BT Sport.

"You've just seen 90 minutes of boring, defensive....I've tried to defend this team now for the last two or three weeks, it's getting more and more difficult to do it because every time you come to Old Trafford this is what you see; negative football.

"I see square pegs in round holes with players in the team. There's so many question marks over the team.

"The only thing I can say is I'm glad I don't have to go to Sheffield a week on Tuesday."
