Bishop admits Redknapp revived his career at Dean Court before leaving for City.
He told the Cherries match programme: "Harry resurrected my career. He gave me the freedom to play and would just tell me to go out and do my stuff. There were no particular orders or rules for me.
"That season put me back in the window and for Harry to give me the chance to play on that stage again was great. I loved playing there and it was the springboard for me.
"Harry heaped a lot of praise on me during the season. I know how much he valued me and he was pushing me to play for England. When you see and hear things like that from your manager, it lifts you.
"I will always be grateful to Harry for what he did for me during my time at Bournemouth."
