There was a lot of controversy😳 during Arsenal's🔫 last game at the Stamford Bridge but Arsene Wenger👔 insists his players must focus on their own game⚽. He said it was going to be a combative💪🏻 clash especially with Diego Costa😡 on Sunday. The Spaniard provoked😠 Laurent Koscielny and Gabriel which eventually led to the latter being sent off👉🏼 for retaliating. "We have to be prepared👍🏻 for a battle because Costa gives you a fight💪🏻. After that, it's down to the referee,” said the Arsenal manager.
