6. Michael Owen
In May 1997, Michael Owen was thrown on for his Liverpool debut as a 58th-minute substitute against Wimbledon. Sixteen minutes later he had become the youngest ever goalscorer in the club's history at 17 years and 144 days old (a record only beaten by Ben Woodburn last year).
Four months later, the Academy graduate was handed his European bow by Roy Evans at the famously raucous Celtic Park. The youngster wasn't fazed in the slightest and took just six minutes to score the opener and set the Reds on the way to a 2-2 draw in the UEFA Cup clash.
Within a year, he had become one of the hottest properties in world football, due to his brilliant goalscoring record and an incredible strike for England against Argentina at World Cup 1998.
He was Liverpool's top scorer in the Premier League for seven consecutive seasons and, by the time he left Anfield for Real Madrid in 2004, he had won a treble and the European Footballer of the Year award.
