"It was the biggest night of my career and I came to Liverpool for nights like this. It is unbelievable - the high tempo of both teams, the fans, everything," said the striker.
"It was special for all of us because of the work that we put in. To score four goals against a very good side is a good achievement for us and we are all very proud.
"It was a great game for Liverpool and for Arsenal but the most important thing for us is that we are now in the semi-finals."
