Manchester United defender Rio Ferdinand is almost certain to take his place in the starting line-up for the important Champions League quarter-final clash with FC Porto. Ferdinand has missed the Red Devils last three matches but looks set to come in for Wednesday's match in Portugal.

"We think Rio is fit," said manager Sir Alex Ferguson.

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

"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."
