A former Manchester United player has spoken about his ex-colleague Cristiano Ronaldo, whom he found to be a frustrating figure at Old Trafford.
Having joined United as a teenager, the Portuguese attacker did not always have it easy in Manchester, especially in his first few seasons.
One of the club's former players, Jonathan Spector, recently recalled a time when Ronaldo was not the superstar he is today, a time when his final product caused frustration for his teammates and United supporters.
"He was a frustrating player. You could see that he had so much ability but that he wasn't a finished product just yet," Spector told AmericanGambler.com.
"I think he owes a lot for the player he is today not just to the manager but the players that were around him.
"(Sir Alex) Ferguson did a great job of having players in the team that could help the players around them, make everyone around them better players.
"I think those formative years in his development to make him the finished product; he couldn't have been at a better place than Manchester United.
"You could see his final ball wouldn't quite be there, you could see at times Ruud van Nistelrooy might get really frustrated because he didn't know how many step-overs Ronaldo was going to do before putting the ball into the box for him, but his ability on the ball, to beat players one-on-one, it was clear to see that he was going to be a very special player."
Ronaldo scored six goals in his first season at the club, and scored nine times in his second campaign. It would not be long before he became one of the team's most prolific scorers, striking 118 goals in 292 matches for United overall.
The forward joined Real Madrid after six years in England, going on to become one of the greatest players football has ever seen.
