@Castreal why you use blue on DC and red on ST? It doesn't make sense, because ST will always join attacking (with or without arrow) as well as DC defending part of game. I use different setup. For example, look at modern fullbacks, they join attack a lot, so red arrow on them is quite usual. Why not blue arrow on ST for 3ST formation (I know you're talking about 4411 but this is hypotetical)?
Look at Wayne Rooney; he is attacker who gets back in defence. I can't find link now, but there was short insert from last duel between ManUtd and Liverpool where he acted as a defender few times. He has great work rate, that is why I sometimes use blue arrows on ST or AMC, to help team in defence (if I have 3ST or 2ST+AMC).
There is thread about arrows, so you can post there:
