A former teammate of Dibu Martinez criticised him for his gestures in the match between Aston Villa and Lille

Former attacking midfielder Samir Nasri, who shared the squad with Emiliano “Dibu” Martinez, criticized the Argentine goalkeeper’s attitude for the gestures he made in the penalty shootout where Aston Villa beat Lille and advanced to the semi-finals of the Conference League. I’m bothered by Martinez’s behavior. I met him when I was young at Arsenal and it wasn’t like that, he was more discreet. I don’t like his behavior at all, he’s very borderline. Now it became his hallmark. You’ve saved a penalty, you don’t need to make fun of the fans by saying ‘SHHH’ to get them to talk about you,” Nasri, who teamed up with the World Cup winner, told French TV.Nasri criticised Martinez for his gestures in the second leg of the Conference League quarter-finals.
The goalkeeper of the Argentine National Team was booed by the local fans throughout the match and at the time of the penalty shootout he excelled by saving two of the shots of the shootout. Once the match was over, Martinez retaliated by celebrating with one of his famous dances. It should be noted that Aston Villa won 4-3 in the penalty shootout against Lillie and advanced to the semifinals of the Conference League. The series was defined in this way because they had drawn 3-3 on aggregate.
