It seems SI have fixed using a back 3. So far I've had success so far using the direct 3-4-3 that Napoli use, with San Marino. And the controlling 3-5-2 the Juve use, with Cardiff.
Anyway, I may be wrong but it looks like no ones uploaded any proper back 3 tactics yet so i was wondering if anyone would be interested in the tactic that brought these results (both with newly promoted clubs) :
