In my short Topeleven career, there is only one formation that annoys me the most as I have a 0% win rate against this.
5-3-2
It's like a bane of my club's existence.
In Season 3, Level 3, this formation steamrolled the league with a 25-1-0 record, scoring over 100 goals. I met him twice that season and lost 4-1, 0-4, using 4-5-1 & 3-5-2.
This season, I was knocked out of the cup by this formation (Level 7 vs my Level 5 but similar squad strength). Despite dominating - having 70% possession in both legs, he still matched my total shots/on target, and scored 2 goals in each leg.
I was knocked out 4-1 on aggregate.
1st leg defensive 4-2-2-2 using ML, AMR, MC, AMC, lost 2-0, final possession 63% to me, but he created more chances (?)
2nd leg normal 3-4-1-2, lost 1-2, final possession 69% to me, matched my chances created (??)
Anyone else annoyed with this formation or had some success against it?
