Real shame.Yup. I heard exactly the same story from two other sources (one who works for the NI FA, and a former team mate at Glenavon). There was never any issue with Sykes playing for the NI age groups, and no-one ever heard him say he didn't want to play for NI. The NI FA were furious and believed the agent had cooked up the ROI story to get a move. There had been very little interest in Sykes from the ROI. He may get into a squad one day, but he would have got 40-50 caps for NI. Not the best move he will ever make. NI are so angry at the way he pulled out that they would probably not have him back even if he changed his mind, apparently.
He has come of age this season on the pitch.
It sounds as if his agent really didn't do him any favours. It is a small industry and I assume that mud sticks.
