Perry Groves criticised the lack of leadership in the Arsenal squad after they lost their second game in a week.
Neal Maupay scored the winner at the injury-time and helped Brighton to move from the relegation zone and completing a first league double over the Gunners.
Maupay calmly lifted the ball over substitute goalkeeper Emiliano Martinez to make the scoreline 2-1.
Nicolas Pepe made a superb strike to put the Gunners on course for a much-needed victory in their pursuit of any European football, but just few minutes later Lewis Dunk the equalizer.
We can easily say that it was a miserable day for Mikel Arteta's side as they lost one of their best players in the early stages of the game. Bernd Leno was forced off the pitch after he got serious-looking knee injury.
Former Gunners winger Perry, who watched the game for talkSPORT, said: “It was a goal of the highest quality from Brighton, a brilliant, brilliant finish from Neal Maupay.
“But they’ll be big questions asked about Arsenal now. They couldn’t hold onto a lead again and their game management was really, really poor.
“To be leading and to keep hold of that lead, you need leaders, and I don’t think there’s enough leaders in the Arsenal side.
“You need to have players screaming at each other to make sure you’re not left in 1v1 situations, like Cabellos was in the build-up to the equaliser.
“To be fair to Brighton, you have to say their winning goal was absolutely top quality and sometimes you just have to take you hats off.
“Arsenal had blocked shots before that, but the goal was just very clever play. Sometimes other teams just have that little bit of quality.”
