It's fair enough if you ask me. Arsenal are such an awfully run club it's bordering negligence. How you can let your 2 best players run down their contracts is beyond me. I feel sorry for the fans as they're ripped off more than most and have had to put up with a lot of turgid performances for the past 10 years whilst paying a huge premium for their not so new stadium. I have mates paying the best part of £2k for the privilege to watch a mediocre team.
As for Sanchez himself, I'm not sure he gets in our best 11 as it stands. Don't think you can immediately shift any of Sane, Sterling or Aguero, especially given the performances he's put in for Arsenal this season, although some might argue he's not been as good because his head's gone.
