Arsenal are fortunate to have a goalkeeper as great as Raya who was able to ward off an Atalanta player's penalty kick and followed it up with a classy save when blocking the rebound. If it wasn't for him who performed brilliantly under the crossbar, perhaps Arsenal would have lost at Atalanta headquarters. Yes, maybe Arteta prefers to play cautiously to prepare his team for another Big Match against Manchester City in the EPL. Arsenal back line plays very well but was not matched by the midfielder and front lines, perhaps this is a lesson for Arteta who does not want to bring in a new striker at the start of the season.
