Kuyt scored the winner for Liverpool in the 1-0 victory over rivals Everton in the Merseyside derby on Saturday.
“It’s a great feeling and I’m really happy to have scored 50 goals for the club, especially in a game like this,” Kuyt told the club’s official website.
“But I don’t think it mattered who scored, just that we got the win.
“I think we showed belief when we had 10 men and that comes from the confidence we have built up over the last few games. We had to believe that we could still win the game and we did that.
“Out of the last seven matches we have taken 17 points and have kept six clean sheets, so you can see from those results that we are playing better and our confidence is up.
“Now we have to keep going and make sure we are ready for the next game at Arsenal.
“We’ve had a massive win and we will enjoy the victory. But after that we must focus on the next two games which are very, very important.
“We have to show that we really are back to our best form.”
