Henry has verbally agreed to take charge of the Championship club with Bruce holding talks with Aston Villa bosses today over his future.
The Frenchman is the favourite to take over should Bruce get the chop but there are fears his lack of managerial experience may see him struggle in the Championship.
And Bent, who made 61 league appearances for Villa, fears it’s too risky to be appointing Henry as the club’s new manager with their primary focus getting promoted back to the Premier League, having suffered heartache in the play-off final to Fulham last season.
“For me, if you want to get a team out of the Championship you stick with someone like a Steve Bruce or a Neil Warnock – they have pedigree of getting teams out of that league,” he told talkSPORT.
“For Villa to take such a big risk and appoint Henry – I know he’s legend, he’s my hero being an Arsenal supporter – but as far as managing goes he’s untested and he doesn’t know the Championship.
“He’s played games in the Premier League and Champions League, but the Championship is completely different to anything he ever faced in his career.
“So for them to turn away from Steve Bruce, someone who has experience, has done it before and know the league inside and out, and to all of a sudden taken a gamble on someone like Henry – it’s going to be tough for villa I think.
“Hopefully Steve Bruce keeps the job. I think he could definitely get Aston Villa up this season.”
During Bent’s time at Villa he worked under Manchester United legend Roy Keane, who acted as assistant coach under Paul Lambert during his time in the Midlands.
And while Bent admits he learned a lot from the Irishman, he claims Keane didn’t understand his players not being able to match his own career when things got tough.
“There are so many risks involved [if Henry takes the job],” Bent added.
“The standard Thierry is used to, from his playing career and from his coaching work with Belgium, is going to be completely different.
“I’ve had it before [being coached by a manager who used to play] and at first, when things are going really well, it works. The standards are set high.
“But it’s when things start to go badly going that you start to see all the problems.
“You begin to think, ‘his expectations are way too high’, so you start to get frustrated and then the manager gets frustrated because they can’t understand why we can’t play the way they played when they were playing.
“It becomes a struggle until the whole thing just implodes.
“I had Roy Keane at Villa – he was a fantastic player with great ability and he was a good coach.
“But one of his problems I always felt was he just couldn’t understand why the midfield players in our team weren’t as good as him.
“Even with simple things like possession drills and shooting drills, if we missed the target or gave the ball away, he couldn’t understand how we could make such bad decision.
“In the end, ultimately, he left.”
