I never use in depth tactics, I usually just tweak the formation to my liking and play a standard offensive possession game in a 4-3-3 system. When I start using lower teams more in depth or play on legendary rather than world class I think I'll be a bit more studious; I favor medium to high working, fit players, and I prefer wingers that track back defensively. I'm open to counters because I use attacking fullbacks but I don't really attack on the counter, I prefer to break down the defence bit by bit. Might sound bad but it works.
Does anyone else use their virtual pro in manager mode? None of my friends even create one lol. It's a bit unfair with mine because he can play any offensive role and retain an 87-89 overall if you change his base position. I'm starting to think that playing without him might make it a lot more challenging - in a quiet season, he scores and assists at least 40 goals in all competitions!
