Giroud did not miss two sitters, he missed one good chance before the end of the match.the first header he missed was far from being a sitter. (justarsenal.com)
Should Sanchez score at the first header then game could have gone totally different. (justarsenal.com)
His first header on goal was very impressive and the keeper just made a spectacular save to keep it out. (justarsenal.com)
