Redknapp played with Ince's Dad, Paul Ince, who is now manager of the Magpies and took his son on-loan from Liverpool last month.
In his column for the Daily Mail, Redknapp wrote "What a buzz that must have been for my old mate Paul Ince to see his son Thomas scoring an 86th-minute cracker in the 2-0 win over MK Dons.
"Incey is settling in at Notts County and deserves another chance as a manager. He has lots to offer the game. He'll enjoy having Thomas there on loan, but they will both hope it's for the short term, so the lad can return to Anfield and make a breakthrough."
