Been reflecting on it, and I don't think O'Nien is necessarily miles below this as some are saying, but I do think his strengths don't fit this team as much as they did in the Championship.
Where he excelled in recent years was in games where we had 50%+ possession, being calm on the ball and moving it out of defense, being brave when teams snuck in behind, with a bit of shithousery to boot. We're now a much, much more conservative team and being organised defensively and staying switched on it what it's all about. I don't think he's at the age, or going to get the game time to ever adapt to that now sadly. He's also a bit hot-headed to say the least, and definitely a player that "grows" into games - so coming on as a sub just might not suit him.
I really hope it's not over after this, but the timing of this ban with AFCON and January on the horizon means he's likely to be replaced sharpish and those cameos likely will be few and far between now.
Will always love him to bits and a rash challenge like that won't change my opinion one iota on his importance to Sunderland.
