Just make shite up and hope it sticks; like the 'big games' myth as if winning big games is some indication of a successful season (hint it isnt).
Just to add on to what
@Pogue Mahone said let's look at SAF record against Chelsea, Liverpool and Arsenal when he won 3 league titles in a row. This was when the Premiere league was considered at its peak because there were so many strong teams in the league so don't give me shite about how the top 6 are now amazing or whatever.
2006/7:
W2 D2 L3, 1 win away from home
2007/8:
W5 D2 L1, 1 win away from home
2008/9:
W3 D2 L3, 1 win away from home
If you are still so far up your own arse that you cant see the trend, lets move to later years where City replaced Liverpool as a top team.
2010/11:
W6 D1 L3, 1 win away from home
2012/2013:
W3 D2 L4, 2 wins away from home
If you are not stubborn, but just an idiot then lets make things more simple for you by looking at the Champions last year and their record against the top 6.
W7 D1 L5, 1 win away from home
Games against rivals is a coin toss and the difference between a good and bad result can be from one moment. Big teams have players than can hurt you, which means that you will definitely lose to your rivals, especially away from home where they have the backing of the fans and a psychological edge.
We will definitely lose to a top 6 side this season, and it doesnt mean that we are shite and the manager is clueless. We will also get played off the park in some of these games because top teams have the quality to do that. We will also play other top teams off the park because we have the quality to do so.
