Corinthians youth chief Afonso Luiz Armonia has concerns over defender Dodo's move to Manchester United.

The 17 year-old's move was confirmed this week and Armonia admitted: "I don't want to be negative, because it may be good for both sides, but I think he is too young for this sort of thing.

"It's difficult to know if a youth player is ready for such transfer business. A boy of 17 years should be allowed to play without pressure."
