I would agree. He was mostly solid (made a couple of mistakes) but rarely spectacular. He was one of Bolton's best players though in a night where few of their team shined.
My only worry with Joey is that he looks much bigger and more sluggish since his long lay off for his injury. I remember at Sheffield Wednesday he looked more dynamic and seemed to have an extra yard of pace. He scored a few goals there also. I hope his injury isn't continuing to have a negative effect on his development.
Saying that if O'Brien is regularly playing the holding role for Bolton though (as he has been doing for the last few weeks) I'd stick him in the Ireland team ahead of Carsley who I think is a nothing player. Joey can at least pass the ball and is decent in the air (useful in a midfield of short arses). I'm aware he was rubbish against Cyprus in the same position but he hadn't played there for Bolton at the time in a long time (about a year and a half).
