Yes it is really crazy how easy people jump on players. Fellaini, Lingard, Rojo, Smalling, Young, Jones have all been scapegoats. It seems people always need to find someone to blame rather than focus on the team.
Most of these scapegoats have shut people up though recently with all of these players having done really well this season not just in performance, but actually scoring goals and getting assists, or conceding few goals which seem to be the main metric that these type of people use when they judge.
Lindelöf playing really well now too. Not sure who people will target. Maybe Rojo again. Mkhitaryan could be the next one, but I hope he find some good form again soon. Mata and Herrera seem to be key targets now as well, but I hope and think Herrera can have a big games against City.
