Yes, exactly the point. I had noted that you didn't play too well in your first two games, so the win against Man City was a huge surprise (One that you have to be quite proud of, mind).
As noted, the main goal is to beat those around you. Anything you get from the Top 7 is a bonus. No one is going to remember that great win against Man City away if you bomb against the Villas, Hulls and West Broms (No offense to them, they'll be thinking the same thing). Same case for us, we put in a great shift against the top teams, but getting results from those around us are of utmost importance. You're not only winning points for yourself, you're talking points off your rivals.
It is going to be an interesting test, can Leicester convert their form against the top teams into points this weekend? Can Stoke properly kick on after their win against Man City? The next game will tell a lot.
