The American businessman announced his intentions to part with the club in the summer, but questions over whether he had a change of heart arose after Lambert was offered a new contract this week.
"If something did come in a month, two months, three years, Randy will do what he thinks is best for Aston Villa," the Daily Mail quotes Lambert as saying.
"If that is to sell it to a beneficiary who will make it stronger that hasn't changed but he's right on it, right with it. He's always loved the club. I don't think anyone should be under any illusion about that. He'll tell me things when he needs to."
This weekend, Villa will take on Arsenal on home turf.
