problem with team average

Hello everyone, im writing because I'm confused.
im noticing differences between the average of my team shown on the main screen, and the one shown in the support screen.

im are a 6-level manager with an average of 50.2, the worst player is 48.

Now, when with my brother's account i'm going to cheer for the game, my team average is 46 .. and I lose a lot lately.

how can be?!??! bug ??

ty in advantage

Need screen shots but I'd guess that one is the average of your full squad, the other the team you are putting out.

the main screen you saw is the first 11 you put on the field for next match ..... which is not counting the sub..... while your brother/ friend or even yourself (second team ) come into the game to support they see the total average....which also include your sub ....
