Ferdinand made a major mistake in Saturday’s 1-0 defeat in Ukraine and also against Holland in August and in the Manchester derby last month.
“I spoke with Rio on Monday and I spoke with him again,” said Capello.
“I asked him what happened against Ukraine and I spoke with him about the moment when we conceded the penalty.
“And I’ll make him watch the DVD of the game again to understand what happened and I will see the mistakes we made.
“I only spoke with Rio about Saturday’s game, not the one in Holland or any other.
“But I was not tempted to leave him out against Belarus. He is fit and will be in the starting XI because he is one of the best defenders in England.
“He is a really good man, a big man, an important player for England and for United.”
