You are right to an extent,the problem is McInnes sets up the team to protect the likes of O’Connor and Considine because he knows they will struggle if we are set up to attack teams.Thats why we play with 2 holding midfielders and 1 striker even against the diddy teams.
You could say like Arnason both Considine and O’Connor aren’t good enough for us if we want to improve,2 of them are gone,Considine is still here and O’Connor would be if he wanted to.It isn’t because those 2 are better than Arnason it’s because McInnes likes them and didn’t like Arnason.
A manager shouldn’t be picking players on the basis of how much he likes them on a personal level.
