Manchester United boss Sir Alex Ferguson is delighted with the injection of youth into his squad this season.

"These young players like Rafa and Fabio (Da Silva), (Rodrigo) Possebon and (Danny) Welbeck are the ones we have always tried to have here in the last 15 years," said Fergie. "They are the 20-years-of-age mark and under, who can take over from the ones in that group now who will become the mid-age range players. The mid-range ages become the older group. That is all about managing change."
