Manchester United boss Louis van Gaal was not entirely happy with his side's performance in their easy 3-0 win against Liverpool.
The Red Devils registered their sixth consecutive win as they keep the pressure on leaders Chelsea and rivals Manchester City.
But the Dutchman says he will meet with the players to understand why possession was given away "unnecessary" throughout the match.
"I'm proud we have a clean sheet but that is also because David De Gea has superb reactions," van Gaal told Sky Sports and BBC Sport after the game.
"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.
"The last training session gave me a new injury with Marcos Rojo and it was unfortunate to change my line-up again.
"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.
"We gave unnecessary balls away today, that's not good. I will ask the players tomorrow why. I'm very happy but the next match at Aston Villa is important. We have had difficulty in away matches."
