I think the big difference this season with RS is their mentality, they are now able to grind out wins when needs be against the lesser teams, whereas last season they couldn't. That's the difference between them and City, City are bottling it, the RS will know see a point at City as enough, and they'll grind one out.
When City are in flow it’s very hard to grind anything out, the only way to get at City is to go toe to toe with them. If you think City are bottling it now, wait for the RS in a few weeks!
