How's this formation legal?

I just drew 3-3 with a team with 3W-2CDMs-2N-2(AMR,AML)-1 .hows it legal?

I don't see anything wrong with that formation. That person ticks all the boxes - at least 3 defenders, at least one player but no more than two on each flank, one CM, 4 players on the opponents side of the pitch and at least one striker. What is your possession like?

I dominated the game. 64% possession. He got 2 yellows,I got none. He scored from 2 set pieces too. Lucky bagger.

Then that's just the game engine up to its old tricks then. Unlucky there mate. I'd say fight fire with fire and get yourself a set piece specialist as well, my corner kick specialist had notched up 28 assists in 22 matches so far.

I just bought an 18 year old fast trainer. He's a striker & I plan on giving him a free kick specialist trait. Maybe even a AMC trait.
