I don't think Jose intended to ignore Kalas it was more bad luck than anything. He was injured at the start then missed the Swindon match were he would have likely played, then he was fit for the next round but, again unfortunately for him, we were at The Emirates, then after that Gary and John established themselves as the foundation of the team for the rest of the season. Im sure Mou was being genuine when he said Kalas would start twenty games, just a series off circumstances prevented it happening. Also with Huth, Mikel and Varane, Jose has already shown in his career he will give a young player an important role under the correct conditions.
