It was a debut to remember for the world's most expensive defender as Van Dijk immediately began repaying his £75m transfer fee by scoring Liverpool's winner in a 2-1 FA Cup third-round triumph over Merseyside rivals Everton.
"It is still one of the best moments of my career," said van Dijk. "I made my debut for such a big club. It was a massive week for me anyway so to make my debut and score the winner was fantastic."
Is he the best defender in the world at the moment?
