For anyone that's interested in middle team / underdog tactics, I've managed to put something together that so far is working well. I've been doing a lot of experimenting with QPR, mostly on the demo but now on the full game. This is the best I've come up with so far:
The tactic aims to balance between possession and counter attack. Against weaker opponents, it's been achieving 60% possession, pinning them in their half. Against teams that bring the game to us, we've been terrorising them on the counter.
Will keep everyone updated on how I get on, some tough games ahead!
