However, the Dutch striker was fortunate not to concede a penalty in the second half when he appeared to pull back Alexsandr Hleb inside the area.
"It's just a split second you have to decide," said Kuyt. "I didn't pull his shirt. It was never a penalty - but it was close."
Speaking about the game, Kuyt added on Sky Sports 2: "We did everything we could - we wanted to score and we did.
"After the goal, we came back in the game and had a few other little chances. They have a great performance, and we did everything we could.
"We have shown in European nights at Anfield we were really good and we hope we can do the same next week and go through to the semi-finals."
"It's difficult to understand how we did not win the game, we had a lot of possession and a lot of chances," Wenger said on Sky Sports 2.
"We were a bit unlucky as well with a big decision of the referee on the penalty. It's difficult to take but we have to swallow it.
"Sometimes the referee is in a bad position but he was five yards away from Kuyt and it was 100%."
