Absolutely it shouldn't. Fresh in the memory for me is the way Doku kept getting into great defensive positions for City against Chelsea on opening weekend.
You've got to work both ways. Just as a good striker will chase lost causes, a good wide player will track his runner just in case too. It's not even necessarily a just in case, the ball direct to Mitoma was on because Amad wasn't paying enough attention.
Still, like I said, young and learning and perhaps he wasn't thinking too clearly because of what had just happened in his personal life.
