Understanding analysing tool

[fmaddict4ever]

I'm struggling to understand this part of the tactical analysing tool. I'm managing Reading - what represents my offensive focus on the picutre to the right? Cant figure out, whether I'm the blue or the red arrows, and how to understand that section.

If your team wore the blue jerseys in that match, then blue arrows show how much each of the 3 areas - left, right and middle - was used by your team when attacking. In this case, it means 57% of your attacks went through the right flank, 11% through the middle and 32% through the left. The same principle applies to the red arrows, i.e. the opposite team.
