Former Manchester United defender Jonathan Spector says that Cristiano Ronaldo was a "frustrating" player during his initial days at Manchester United, but credited the Portugal star for growing into a player widely considered to be the best in the world.
Ronaldo arrived in Manchester in 2003 after breaking through with Sporting CP as he went on to score six goals in his first campaign at Old Trafford before scoring nine in his second season.
