Pochettino has been tipped to replace under-fire Ole Gunnar Solskjaer following Manchester United’s poor start to the 2020/2021 season.
The Red Devils have recorded only two wins out of their opening six Premier League games and are without a win at Old Trafford so far.
Solskjaer’s men were surprisingly beaten 2-1 by Istanbul Basaksehir on Wednesday, bringing an end to their perfect start to the Champions League season.
Pochettino has always been linked to the United job since he was sacked as Tottenham Hotspur manager in November 2019, but has rekindled speculations earlier this week by revealing he is ready to land a new job in the Premier League.
O’Hara believes it would be a wise decision to appoint Pochettino as the new Manchester United boss.
“I think you have to give Pochettino massive respect for what he did at Spurs,” O’Hara told talkSPORT.
“He didn’t win anything, and that’s probably the biggest regret that he has got, but where he took that football club with no budget, not signing any players, producing young players, playing an exciting style of football, made him world-class.
“He made Tottenham a guaranteed top-four side every season, and he got them to a Champions League final. On the night they were poor, but as a manager he is unbelievable.
“For me, he’s the fourth-best manager in England right now, and he hasn’t got a job. The other three? [Jurgen] Klopp, [Pep] Guardiola and [Jose] Mourinho.
“I would have Pochettino in most football clubs – apart from Klopp and Guardiola.
“How can you not say he’s unbelievable? Look what he did at Southampton and look at what he did at Spurs.
“Give him Man Utd’s squad and they would go to another dimension.”
