You have to assume that Arsenal thought they were getting the Mikel Arteta who did so much to turn Raheem Sterling into a goalscoring predator at Manchester City.
If they had done their homework on Arteta, rather than approach him because he was young, Spanish and formerly one of their own, they'd have learned that he was the one who encouraged Sterling to operate closer to the six-yard box and look to score every game, even if that meant missing two or three chances.
Unfortunately for those who yearn for a competitive Arsenal in the mix, it's beginning to look as if Sterling's transformation was more about Pep Guardiola than his former assistant.
