There's a post on TE Worldwide FB Group with a 20-0 scoreline...
Any formation or tactics advice given is based purely on experience with my teams...
I think that I played vs a semi-abandoned team, what means that he have players out position because the contracts of players he had, expired, so the sub's went to occupy the empty spots inside the main 11, and these sub's were from other positions...
I doubt that he was tanking just with a 2nd Gk as dmc and a Mr as DR dont have negative impact.
Then tanking basically, is when you set up a "bad-illegal formation" to lose matches with the idea to don't promote.
i've just saw a 0-16 from my friend...i'll post the screen soon
but i think 0-17 is the max we can reach
