I try it atleast once a season because I'm a fan of AC Milan when they were dominant with the diamond. I can name their 11 off the top of my head.

In my opinion, short passing is better with formations with DMC and AML, AMR and AMC but that's just from my experience. It cuts out mistakes but may limit chances. I'll test short passing, whole press, attack with the diamond in near future and I'll make a post about the stats.
