I dunno. That should be the case but Cesc gets stick for playing for Chelsea despite it be us that rejected a move to bring him back. Before he left most people could understand why he'd want to leave considering the lame League Cup final defeat and Cesc not even being selected for the final.
With RVP, everyone was on side with the player until that open letter. Those guys did a lot more for Arsenal than Sanchez and I can't see him escaping the backlash.
