Patrice Evra has recalled how Sir Alex Ferguson turned Cristiano Ronaldo from a "YouTube player" into a Premier League superstar.
The Portugal international, now 37, joined Manchester United from Sporting Lisbon as an 18-year-old in August 2003. He scored just six goals during his debut season at Old Trafford but soon became prolific - finding the net 23 times during the 2006/07 campaign.
Ronaldo has often highlighted Ferguson's influence on his successful career, which has seen him win countless honours - including seven league titles, five Champions Leagues and Euro 2016 - and score 700 club goals for United, Sporting, Real Madrid and Juventus.
