Pardon the irony of me making this comment but this is the same manager that has taken you to a new level in the Champions League, including beating AC Milan!!
He's not taken us to a new level, sure we got to the last 16 twice with 9 points but we also failed to make the last 16 with 9 points on 2 occasions.
Look at the teams we beat under O'Neil at CP as well. And we put on better performances.
Its not just the results.
