"I know Bill well, he was very good when he worked with Manchester United," said Keane.
Keane, who discussed his decision to accept the Sunderland job with the psychologist last year, recalled: "It was all very relaxed with Bill. Some players would see him every day, some would see him once a year, some lads had no interest.
"I always enjoyed, and still enjoy, speaking to Bill and I spoke to him when I first got the job here. It's not all psychological stuff, it's just like having a conversation with someone and it was all very casual at United. Bill's a human being as well and we'd talk about all sorts."
Steve McClaren persuaded Sir Alex Ferguson to soften his stance on psychologists when he coaxed United's manager into recruiting Beswick from Derby County where the future England head coach had worked previously. "I don't think Sir Alex was ever too keen on having a sports psychologist," said Keane. "Bill was down to Steve. But I've spoken to lads who knew Bill at Derby and they appreciated his work."
