Sir Alex Ferguson has recalled how Cristiano Ronaldo's dazzling debut for Manchester United gave him an almighty dilemma ahead of their next game.
The Portuguese star was only 18 when he announced himself in English football with a 30-minute cameo off the bench against Bolton Wanderers in August 2003.
Ronaldo, just signed from Sporting Lisbon, had the Old Trafford crowd spellbound as he tore the Bolton defence apart and left the pitch to a standing ovation.

But legendary United boss Ferguson has admitted Ronaldo's performance caught him out and he knew there would be a clamour to start him in the next match.
