I haven't been Cardiff on Fm14 but I know our squad very well. Try and go with a 4-3-3 seen as you have Zaha and Noone on the wings (presuming you are on the update) and you have a very good defensive midfielder in Medel (shame he isn't that good irl) and a good young BTB player in Mutch and a decent play maker in Whittingham. Utilise the flanks as well, Zaha and Noone are good, pacey dribblers.
A 4-4-1-1/4-2-3-1 can work well too and if you can develop Dhaeli well you'll have a very good CAM.
As for shouts it is difficult because I don't know how you want to play. You could play counter attacking knocking the ball out wide for Noone/Zaha or you can play a more possession based game because we have capable passers.
