I really like the Cruyff-style 3-1-2-1-3 / 3-4-3 Diamond. You can use the pre-existing one and move the LM and RM to LCM and RCM. You need wingers with high stamina so they can track back to add numbers when necessary. The outside 8s should be set to defending wide if needed. The CDM should stay back and the CAM needs to make runs into the box, while the ST stays on all default setting plus stay central. I've always played it with max width and the highest line possible, plus possession style of course.

What I like about it is that it's the opposite of all the sprint forward kind of Fifa play that lots of people use. It's much more tactical and technical in terms of passing and watching player movements.
