Move Otasevic to AMR and Espana to AML. You will be able to make better use of the entire attacking pitch.

If you go 3 at the back, don't put up arrows on the fullbacks. Unless your opponent has an AMC, you should use 4 defenders as opposed to 3 defenders and a DMC.

I also recommend putting arrows on your MC's. If you put down arrows on them, they will have a higher defensive workrate. You probably don't need to put up arrows on them with so many attacking players, but if you ever go with a V, you can make one of your MC's more attacking.

Everyone else in this thread also has good ideas!
