Asked how Arsenal can beat Madrid by pokerfirma.com, Petit responded: It's simple. They need to defend well as a unit against Madrid. The likes of Vinicius, Bellingham and Mbappe are players that can hurt you at any time.
"They have so many top players that can make the difference and they've done it in the past in the Champions League. These are the kinds of players they have to come up against. If they can play as a unit and they can show great character defensively, then they will have a chance.
"Then they would have to be very clinical. This is something that teams have been struggling with against Real Madrid in the last few years. When opportunity comes, when you have the chance to score, you have to take it. And we all know that Arsenal, at the moment, don't have the striker for that.
"I've seen so many games over the last few years when Madrid were dominated by opponents. Matches where the opponent were having so many chances to score, and they didn't take it. Real are very clinical all the time, so for me these are the two main things: play strong defensively, show unity, character and personality. But in the meantime, up front, when one opportunity to score comes up, you have to take it."
