Rio Back For Porto Clash

United boss Sir Alex Ferguson has confirmed that Ferdinand has recovered from the groin injury which has kept him out of the side for the last three games and will be named in the starting line-up for the match in Portugal on Wednesday night.

We think Rio is fit," said Ferguson.

"He trained on Friday, Saturday and Sunday and he will start.

"There is a lot of quality in Rio's game, so he is obviously going to make a difference.

"Also it gets us back the partnership between Rio and Nemanja Vidic, which has been the cornerstone of our great defensive performances this season.

"That is the difference he will make."
