Both strikers were outstanding on the day.
"It was very special to score a hat-trick, but I have to thank my team-mates, and especially Luis, who played brilliantly," said Kuyt.
"His influence since he arrived here is really good. He scored in his first game, he was very close to scoring against Wigan and he created a goal against West Ham for Glen Johnson.
"For him to be at his best after just a couple of weeks at the club is impossible.
"But he has shown the will he has to be a great player for Liverpool and I think there is a lot more to see and expect from him."
