So lets see the report from Bleacher for that period ... not something that suited your agenda showing 4 games less.
OK. It doesn't read well for Sanchez.

Whatever period you take, and whatever stat you use, I think you'll find his game has taken a big dip on previous seasons.
I don't know why you are so hostile to discussing this. I am not dead set against signing Sanchez, but it doesn't enthuse me. I think we have identified the need for a wide forward or an attacker we can do better. Maybe not now, but in the Summer. Even now I would prefer Mahrez. If Sanchez does come to City, that's probably the likely way it will happen: mahrez to Arsenal, Sanchez to City.
Would you seriously start him ahead of Aguero/Jesus or Sane, Sterling, Bernardo Silva, KDB, David Silva? All it does is flesh the squad out for League Cup games, and FA Cups and possibly only for 1 season. Digest the league table. We are miles ahead of Arsenal, and this season Sanchez is not their best player. Not in my opinion anyway. Unlike the Sanchez is God tribe, I an back my argument up with stats whereas all you have is previous seasons. If we were buying Sanchez from 3-4 years ago, no argument, but he's 29. Players age, and all I am arguing is e wary of that. Little consideration seems to be given to that
