What would you do with this?

thank you good sir!

Defensive/attacking mentality changes only if someone gets more shots on goal and possession? what if you play at home, does that matter at all?

Playing at home will give you bonus possession, but won't necessarily give you more possesion overall. You have to watch the bar and which way it's going. Also look at the number of shots. If you see that he has more than you, switch into a more defensive mentality with counter attack. It should help to keep your defense strong and take advantage in spaces in his offense to score.

how about arrows? do they really matter? or adjusting your Orders is more important?

Arrows will help you to put more pressure on some areas or have some players reinforce defence or offense. I like to put arrows only if I know I'm sure to have an edge on the game and I want to increase it.

Thank you El Duderino for your HUGE input here. Truly appriciate it!

No problem ! Post the result once your match is over!

Had a guy playing just like that -

Beat him by playing

5-3MC-1AMC-1ST

because his middle is wide open.
So I had a lot of possession and beat him 3-1 .
