The whole of football will think that what City need is a central defender. that is a no-brainer. And Sanchez at 28/29 is not guaranteed to repeat what he did last season. He will find it easier at Arsenal next season because he can run all over, play wing, striker midfield all in the one game, but he wouldn't be able to do that at City.I completely disagree with this.
We haven't even mustered a title challenge for the last 3 seasons and last season we struggled to score goals. Signing one of the top players in the PL who will pretty much guarantee 20+ goals and 10+ assists is a no brainer. There is also the winning mentality he will bring and experience that he can give to the likes of Sterling and Sane.
The only question any City fan should ask is whether signing Sanchez gives us a better chance of winning Trophies. I think it's blatantly obvious that he does and therefore anything else is irrelevant.
Sorry. I know everyone disagrees with me, but I can't reply to further posts as I'll spend all day doing it and got things to do
