I think you have to use arrows really, especially with the formation I play. Something like:
--------- ST --------
---W-----AM------W---
------MC----MC-------
---FB-----------FB---
-------DC---DC-------
In that formation, I have both wingers running to the space where my striker is, to give the striker options to pass. I have the full-backs running into the space where the wingers originally should be. I have one of the centre mids on a farrow to the AM slot, and a MC dropping into the defensive mid hole. Occasionally I'll have my AMC running into the striker slot too.
Works well and won me the Champions League with Atletico Madrid as well as finishing in the top four for four consecutive seasons (missing out on the league title by two points in my final season).
