"Manchester United are getting a truly remarkable kid," Jorge Paxaio told the Daily Mail. "Remember that until he was 16 he was just playing with his friends. He has developed incredibly quickly. The first time he plays for United - and I am sure he will make it there - people will notice him because he is different. He has skills that not many players in that League have.
"He is also physically imposing. He will be like [Cristiano] Ronaldo in that point of view. But you will have to wait for him to be ready. I don't just mean in football terms, but mentally.
"One day he had nothing and then the next day he had everything. That will be a shock to him, even if he hasn't realised it yet. He was living in the shelter every day he was with us. He travelled in by public transport. He was like a child in that way."
Paxaio, now with another Lisbon club, Mafra, revealed: "We used to have a gym and Bebe was in there often. But then one day the players turned up and all the equipment had gone. The club had sold it to pay off debts.
"It will be a different world at United. I only had four staff, no dieticians or anything like that. Bebe used to eat his meals at the shelter so I couldn't control what he was eating. He got food poisoning twice. But he was our diamond, our jewel. Our problem was that we didn't have anyone else like him in the team.
"That was the way it was. I played two systems and both were used to get the best out of him."
