“It's difficult to say why," the Dutch midfielder told Liverpoolfc.com when asked about the Reds' slow start to the game.
“They play differently to Arsenal, with lots of long balls and trying to win the second ball. We made two mistakes and they scored two goals and we didn't create any big chances. That was the story in the first half.
“We expected to create better chances than we did. Sometimes you have the kind of games that it doesn't work, and you have to keep your confidence and look forward."
