City have played 10 games. I do think they are a class above anyone else at the moment, but it only takes 1 or two defeats and suddenly a team can be in trouble.
Sanchez is getting on and will be a short term signing. Not sure it makes sense for anyone when he's not playing well. He's had a lot of criticism for his performances for Chile, and he has one goal for Arsenal, against Everton. Why would City want him when Sterling has got 7?
Ironic thing is that Everton need strikers to score goals, but if they do that it makes it more likely that they will lose their place. No top striker is going to a team in the relegation zone, but a mid-table Premiership club is another matter.
