Georginio Wijnaldum: "What I realize is that every game is different. What I will do now is enjoy the moment and next week I will focus on Sunderland.
"It's not normal to score four goals in a game. I will try but it will be hard. These are special moments in your career.
"Every game is different but I focus on that. I will work hard because I start on zero. I'll look to create chances and goals.
"It's wonderful, like a dream come true for me.
"If you score and you get a result, you are happier. It gives you a better feeling. To get four, be part of the first win and work hard is great. It will give us a lot of confidence for the next match."
