Sir Alex Ferguson singled out Fabio da Silva for special praise after the 1-0 win against CSKA Moscow.

The 18-year-old Brazilian played what was probably his best game in a United shirt having covered at left-back for the injured Patrice Evra.

"He was absolutely outstanding," Fergie said.

"The boy is a magnificent player at only 18 years of age. Absolutely first class."

Fabio was substituted with a few moments of the game remaining in Russia on Wednesday evening but the United boss has revealed that he was not injured but only suffering from cramp.

"It was just cramp, he's okay," the United boss added.
