I'm not sure a fully fit Phil Jones would improve us anyway despite how bad Maguire is, I think that's why a lot of people want rid of Jones, we've got to be looking to bring players in that will improve the starting XI not giving spots in our first team to players who won't improve our squad.
With our current crop of players we are struggling to a 1-0 win over Norwich whilst everyone else is thrashing them (Arsenal 5-0 for example) & drawing with Newcastle which quite easily could've been a defeat.
