Lukasz Fabianski produced an abysmal performance between the posts.The second goal Arsenal conceded was a ghastly parody.Fabianski caught a ball passed back to him by Sol Campbell.Porto earned an indirect free-kick for that bit of lunacy.Ruben Micael passed the ball to Falcao who put the ball past Fabianski while he was getting back to to his goal line.The rest of the Arsenal defence didn’t get time to get back.Fabregas summed it up as a “schoolboy performance”
