There had been speculation that the Manchester United star would not feature in the Euro 2012 qualifier, but Capello has confirmed the striker is "happy to play".
Speaking at a press conference, the Italian said: “Yes he will play. I spoke with him and I monitored him during the two days after the game against Bulgaria and he was really, really good on the pitch.
"He will be in a good situation tomorrow because I hope the performance of Rooney will be the same that I saw in Wembley.”
He added: "I spoke with him and he is happy to play.
"For the reason, I know when the players want to play it is really important for me."
The Manchester United striker is the latest in a series of England players to dominate the front and back pages, and Capello stated he concentrates on his player's performances on the pitch while leaving a separation between their public and private lives.
"The players know what they have to do with their private life. It is their private life, though," he said.
"The players know what I ask of them usually but also, for us, it is really important the performance on the pitch.
"It is better to separate the different moments.
"It is good for us that he [Rooney] is here," added Capello.
"For one player to stay here at this moment is really important. I spoke with him, he said he was focused and that he wanted to play against Switzerland.
"I am sure tomorrow he will play a really good game, the same level as he was against Bulgaria."Moving to footballing matters, Capello stressed the value of gaining three points in Basle on Tuesday night.
He said: "Every victory is important. Switzerland will be important as they are one of the strongest teams in the group.
"Every game we have to win as this group is really balanced."
The 64-year-old has an impressive record as England manager in qualification matches, with 10 wins from 11 matches, and is fully focused on securing a spot at the European Championships as soon as possible.
"I try to do everything very well. We have won a lot of games but we have lost some important games," he added.
"The future is up to the players always as I can prepare everything but the game does not go as you think.
"My target is to play at the Euros and it is important to arrive first in the group."
