Walcott was critical of England coach Capello for the way he was treated leading up to being axed for last year's World Cup.
"I didn't have a clear-the-air meeting with the manager," said Walcott. "I saw him in Italy. We had a laugh and a joke about it.
"He said he preferred me as a footballer rather than a writer and laughed it off.
"He was great but I never thought it was going to be a problem anyway.
"He has been great to me. There are no hard feelings."
