People need to remember our rate of improvement and look how we have improved as a squad with the likes of Dawson, Diame, Robertson, Jelavic, Hernandez, Huddlestone, Ben Arfa, Ramierez, Livermore, Davies and Chester etc
If that rapid rate of succession is to continue and we want to become an established Premier League team and even in the top half of the league then we need (unfortunately) to put sentiment and cult status aside. McShane and Quinn are okay squad players but they weren't even guaranteed starters in the Championship and in the bigger picture are the players we will at some point need to move on from.
We now have the likes of Tom Ince and Maguire not able to get in the squad and these have potentially massive futures.
