Igor Tudor became the first Tottenham boss to lose his first four games in charge, while the club have lost six games in a row for the first time in their history as fans fear relegation.
The side are winless in 2026 and sit one point above the relegation zone which means Championship football is not far off for the North London side.
Tottenham have not improved under Tudor and O’Hara has opened up on who could step in and take the job on a permanent basis as the club tries to steer away from the drop zone.
“You could bring in Redknapp to manage these players, make them feel like they've got a bit of confidence, a bit of belief.
“You'd need to have someone alongside him who's been around the Premier League in recent years to help him with set pieces and the tactical side of it. But for me, you can bring in Redknapp as a man-manager.
“Or you go and get Sean Dyche and you say, "Listen, I'll give you £5M to keep this club in the Premier League". Because he's been around the Premier League in this sort of moment.'
“I'd rather Redknapp because I know him. I've not been in the dressing room with Dyche.
“When he first came in at Tottenham, we were in a bad spot. Harry put his arm around the players, told them to go and express themselves, made everyone feel like they were superstars and simplified it.”
Redknapp said he would “of course” go back to the club if asked whilst Sean Dyche is said to be reluctant to take on a short-term role according to reports which will worry the Tottenham board.
