Nolan is a very limited footballer, a poor athlete on a good day, and way past his best. A lot of us on here asserted that while his goals were valuable, we would function far better as a team if he was replaced by a midfielder with athleticism. Further to that, a couple of us expressed the opinion early last year that Pards didn't rate him, and he'd be out the door if he wasn't happy to be a substitute. For clarification, Nolan had 2 years left on his contract when he left NUFC.
Basically, there's not a hint of correlation there with Colo's situation. Both are captains, that's about it.
