Possibly a retarded question (PES5)

I'm pretty sure its the attacking/defensive setting. You can change it in game as well, L2 + R1 if I remember correctly.

Red means most attacking and vice versa.
 
The green is the player playing at the most defensive level. The red is the player playing at the most attacking level. Computer automatically updates this according to the situation i.e. if a player has to defend, or if a player is taking someone on. You can manually change it too using some combination of the R's and L's.

Alternatively just read the guide provided with the game.

That's the one I was going for, thank very much.

SiYuan, I wasn't talking about those bars, but thanks anyway - odds are, that would've been my next question! See what happens after two years of not playing it...

Aye, you hold L2 in either case and press R1 to notch up the attack, or R2 to bring it back down to defence.

As I said my idiot cousin lost my guide...
 
I always set them to manuel control in the tactics screen as I hate it when they put it too defensive if your winning in the last 10 minutes.

Your always under pressure if the other guys on red and your on green.

That's why you should turn "Counter attack" on in the last 10mins. You can easily get 3 on 2 breaks and sneak in a goal or two
