Please Explain Red/Blue Arrows?

[Robert Wachowiak]

its should be easy to understand
if you are attacking ->those players with red arrows are going further into next position (as a support)
if you defend yourself --> those players with blue arrows are going "back" into position (as a support)

I noticed i.e. that MC (MR ML) w/o any arrow are not going into the GC box but are passing or shooting from distance (the exception is the corner or counter-attack)

but if I'm right? no idea:/

[Cholo Simeone]

So if you put a blue arrow in a DC, he becomes a GK? The same for a ST and red arrow. No sense.... Arrows... Nordeus best hidden secret...
