Manchester United boss Sir Alex Ferguson is confident Fabio da Silva can make the same impact as twin Rafael.

Fabio, a left-back, has seen his progress hampered by a shoulder operation which has meant he has been sat on the sidelines as his brother has captured the headlines.

"When a guy turns the corner you cannot do anything about it," said Ferguson of Rafael. "I feel the boy has something special.

"He has such character, and such talent, and great courage. He's got that Brazilian mentality where he wants to get on the ball all the time."

But Ferguson admits that he is full confident Fabio will soon produce the goods too.

"I have absolutely no doubt at all that he will do the same for us as Rafael," added Ferguson.
