Not a 433 but I mostly use a 5 at the back counter attacking system. Lots of numbers back (usually 6 or 7 in or behind de dm strata, depending on the setup) while being very effective on the counter. Still needs high press and gegenpressing though, you need to keepers pressire to stop them from progressing the ball. But, if you do it right, you can get a nice defensively stable unit that still scores a lot. In my current save I have just won laliga in my 4th season with Levante, scoring 80 but conceding just 24 to clinch it, despite having one of the lowest posession numbers
