Louis van Gaal: Manchester United still making too many mistakes despite win

Manchester United manager Louis van Gaal takes his seat before their English Premier League soccer match against Liverpool at Old Trafford in Manchester

Louis van Gaal admits Manchester United are still making too many mistakes, despite their sixth successive win.

Wayne Rooney, Juan Mata and Robin van Persie were all on target in a crushing display at Old Trafford as the hosts defeated Liverpool 3-0.

But after the victory, Van Gaal urged his United players to cut out silly mistakes - with David de Gea sparing their blushes on multiple occasions.

The Dutchman told Sky Sports: "I think we have scored wonderful goals. We also kept the shape very good. In spite of the goals we gave a lot of chances away. That was every time we gave unnecessary passes away and that is how we have to improve.

"We gave unnecessary balls away today, that's not good. I will ask the players tomorrow why.

"I'm proud we have a clean sheet but that is also because David De Gea has superb reactions. We scored fantastic goals - one-touch - and I'm very pleased with that."

De Gea drew the plaudits after denying Raheem Sterling and Mario Balotelli on three separate occasions apiece with Brendan Rodgers hinting the Spaniard was the difference in the result.

However, the United boss insists his goalkeeper wasn't the only one to have a decisive effect on the result, with Michael Carrick particularly impressive.

He added: "You can always say that some players are the most influential in a game and of course David De Gea has a big influence. He did it very well but I can mention others who were also very good and had a big influence.

"You can single out as many players as you want. Yes, Michael Carrick did well in defence. I said it was an all-English defence today but then Jonny Evans corrected me and told me his is from Northern Ireland. So a British defence."

"The last training session gave me a new injury with Marcos Rojo and it was unfortunate to change my line-up again. I'm very happy but the next match at Aston Villa is important. We have had difficulty in away matches."
