Always up for hints and tips following my disastrous tender. Currently hanging on to my position, just.
Obviously alot depends on your formation but here goes:
Wingers and full backs come as a pair: if you want to play wingers play full backs or inverted full backs. If you play inside forwards or inverted wingers play your full backs in a full back position but with a wing back instruction. As Boro I play Jones as a conventional right winger with van den Berg as an inverted full back with a defend mentality. I then play my left winger as an inverted winger (miles better than inside forward) with my left back set to wing back support. This replicates our build of 3 2 5 in possession really well cos the right back will tuck in alongside the centre backs when we have possession.
If you play holding midfielders Segundo Volante is the absolute king, especially you want to play more offensively. Having 2 segundo volantes sitting is very strong. If you play conventional central midfielders Mezzala is the one to pick but I play 2 sitting with a 10 so don't ever need to do this. For the 10 I only ever set them to be a shadow striker. They get in the box far more and contribute more goals and assists that way.
For strikers I only ever use Advanced Forward attack. At the start you need to be patient cos your strikers will constantly get caught offside (Latte Lath I'm looking at you) but you can train them beat the offside trap and once they learn this trait they will score loads of goals from balls over the top.
In terms of instructions some are absolutely essential in any tactical set up These are pass into space, higher tempo, counter when gaining possession and counter press when losing the ball. Also important are run at defence and high press. The rest of the instructions are open to your own interpretation of how you want to play. I always play shorter passing, prevent short GK distribution and play out of defence but that is up to you.
The only formations I use are 4231 and a variation of 343 (3 centre backs, 2 conventional wing backs, 2 segundo volantes, inverted wingers with a striker). I've never really had much success with a 433, and as Boro on the new game with have McGree, Jones, Greenwood and Rogers who are all our better players, so playing with a number 10 is essential.
