Apart from having a dodgy defense , Arsenal is unfortunately a team who has dodgy supporters who only see a negative outcome in any game .
Any team in Europa League is not a world beater included Atletico Madrid . If there were that good as people want to make them look , they should be in Champions league.
Against Porto , they showed their vulnerability . A better team than Porto could have taken advantage and scored more than 2 goals .
Antoine Griezmann is a good player but not a super finisher . He prouved against Porto he could miss easy chances as he is just a human .
Moral : Arsenal and Athletico Madrid have both 50/50 chances of reaching the final .
So no panic yet .
