I am assuming you haven’t actually watched Ireland play over the last few months. They play good football for the players that are available to them and were extremely unlucky not to qualify for the World Cup.
They had tough games against Portugal, Hungary and Chechia none of whom would be regarded as weak teams. Coleman played in all matches and was one of the best players on the pitch. O’Brien played as one of three centre backs and was probably outshone by his two partners Collins and O’Shea.
I am not suggesting at all that he be given a new playing contract. In fact I totally agree that he shouldn’t get one but I am surprised that Moyes didn’t make use of him at all during the season based on his performances for Ireland up against some top class wingers.
He offers much more than O’Brien can going forward.
