I seem to have found a formation to use when you play with only 10 men. The formation does a solid job in preventing the opposition from scoring, so when you wanna hang on to a lead (or a draw), this works for me 9 out of 10 times. It is simply a 4-2-2-1 formation with side arrows from the 2 MC’s and none for the DM’s. The lone attacker up front is pulled back and then given a front arrow. This works wonders for me. Try it out.

will try out your tactic next time i’m in a fix, looks good!
i also find the when i’m down to ten, switching to a 4-4-1 is a good option with normal attacking and time wasting set on high.
Time wasting is definately a good thing when youre down to 10. This formation will give you the odd counter attack, but it’s not gonna produce that many shots on goal. I will give your 4-4-1 a try!
