The Frenchman was confirmed as Tim Sherwood's replacement on Monday evening.
The French manager was officially confirmed as the club’s new manager on Monday evening before their game with Tottenham Hotspur.
He has replaced Tim Sherwood at Villa Park, and has a tough job on his hands to save the side from relegation, with them currently sitting bottom of the Premier League table and four points from safety.
His lack of experience is something of a gamble then, and Neville says owner Randy Lerner has taken a big risk with his latest appointment.
“I think it is a big risk,” he told Monday Night Football.
“The logic behind this one is unknown; they will need to explain that to the fans. He’s obviously a good coach but it will be interesting to see how he does.”
The former defender has also questioned whether Villa have the quality in their squad to escape the perilous position they currently find themselves in.
They lost several big stars this summer, with Christian Benteke, Fabian Delph and Ron Vlaar all leaving the club, but brought in numerous new faces to try and survive the loss of their star assets.
Those players have failed to make an impact though, with many now questioning the club's recruitment policy, and Neville has questioned if there is a star man in there that can save them like Delph and Benteke did previously.
“Looking at Aston Villa in recent seasons, they’ve had a saviour in Benteke or Delph, but I look at that team and wonder who is going to drag them out and get them the points they need. I’m struggling [to identify them],” he added.
