Pochettino remains out of work after he was sacked by Spurs last November, just six months after guiding the club to a Champions League final.
The 48-year-old played a key role in transforming Spurs since his arrival in 2014 and indicated on Monday evening that he is ready to return to management having been linked with replacing Ole Gunnar Solskjaer at Manchester United.
But Bent, who scored 25 goals in his two seasons as a player at Spurs, believes Pochettino should not be regarded as an elite manager and believes both Arteta and Leicester City boss Brendan Rodgers are better than the Argentine.
Asked if he considers Pochettino to be a world-class manager, Bent told talkSPORT: ‘I don’t think he is.
‘When I look at elite managers, I obviously look at people like [Jurgen] Klopp, [Pep] Guardiola and even [Carlo] Ancelotti from what he’s done.
‘I can’t put Pochettino in that bracket. Not yet, I know he’s been at Spurs and he’s not won anything at Spurs. To elevate him all of a sudden because he got a team to a Champions League final and a League Cup final.
‘That’s not world level management, for me. I think he’s good but I just don’t think he’s in that bracket. I’d put Brendan Rodgers ahead of him. I think Brendan Rodgers as a coach and a manager is absolutely superb.
‘Arteta, for me, Arteta’s a better coach than Pochettino as well. You look at Spurs and what Pochettino did at Spurs and he took them to a level.
‘When I say Pochettino’s greatest achievement at Spurs, people will say ‘He got them to a Champions League final’ but is that enough? Does that automatically catapult you into that elite bracket because you took a team to a Champions League final? For me, it doesn’t.
‘Arteta has gone in at Arsenal, it’s not even been a year, and look what he’s done there. He’s identified the players that he’s got, defensively they’ve not been great and he’s completely changed that around.
‘[He’s] gone in there and won an FA Cup, won a Community Shield and beat some of the biggest teams out there. He’s managed to find a way of getting it done.’
