Petit is adamant the Italian is the only available manager to fit the bill to replace Unai Emery in the Emirates hotseat.
“In this period of the season, it's not easy to find a manager, a good one. Most of them are already working.
“But we've seen in the past few days that Ancelotti has been fired from Napoli, so it's one of those that, when you see that kind of profile on the market, you must ask yourself the question, 'Is he the good one?'
“Ancelotti would be, right now, the perfect answer for Arsenal. It's very rare to see a top manager like him getting fired in the middle of the season.
“It's a coincidence and sometimes destiny tries to show you the way to go and you have to be open to it.
“He is one of the top managers in the world, he's available and he's on the market.
“In the meantime, the question I ask myself is, 'What kind of manager would be happy to take Arsenal's situation right now?'
“The situation has got worse and worse, season after season, so you need a really top manager to handle the situation right now.
“And, for the moment, the only one on the market and available is Ancelotti. Everywhere he went, Ancelotti had success, except with Napoli.
“He is respected so much by the players for all of his experience and all of his years in the game."
