Ronaldo was 18 when he played the friendly against us and Quaresma was heralded as the bigger talent even then. Many on this forum would've sold Ronaldo and replaced him with Aaron Lennon because he had no end product in 2005. The thread in question will still be floating around.I said teenage talent not 16 exclusively. Anyway I think Cristiano played that game against us at 17, where he played some of the best in Europe and was outstanding, and joined at 18. Outrageous talent and fulfilled it. But there was no doubt he would become a top flight footballer, but becoming one of the greatest of all time was a bonus.
Bellingham is a 16 year old with immense potential for his age. I'm not sure why anyone would be against such a move. Most United fans would be over the moon if Bellingham came anywhere close to replicating Scholes, nevermind the two Ronaldo's, Messi etc.
