"Wayne phoned me on the day of the World Cup final and said he had a great idea," he is quoted by the Independent on Sunday.
"He suggested he could do a TV interview with Ronaldo and they could show everything was fine. I thought it would look stage-managed and said no. Instead David Gill and I flew to Portugal to meet Ronaldo. We told him we'd had a similar experience with David Beckham [after France 98].
"Ronaldo was concerned but not afraid [about coming back]. We said we'd put extra security on his house. He said he'd try it and see how it went. It's been no bother."
