Cascarino told the Express & Star: "I - and many other people who have worked alongside Roy - would tell you that you do initially see him as a No.1, he is a very strong character, very determined. But I think it's a great move for him.
"Roy will be a manager again, I don't see him staying a No. 2 over the long course. I think he is building himself and his career again to be a No. 1."
