First things first, 3 defenders tactics inspired me a lot in the past couple of years and I tried to build one on my own. I didn't call it a 3322 formation because wing backers take an active role in offense, so I considered them as wingers. I did multiple tests with different teams, all in holiday mode (which sometimes caused problems like pushing injured/fatigued players to play as well etc.) and in the winter transfer season, I made some transfers in some saves. I should also mention that I uploaded one of knap's 3 defender tactics (argus I suppose) just to have the set pieces ready, appreciate his work. I believe this one is quite a strong tactic, and when you actually manage the team instead of going to holiday, you'll be even more pleased with the results.
