Using with Napoli, and it's outstanding. Got a fair few red and yellow cards, so I unticked 'tackle harder' in player instructions, and it doesnt seem to have made much of a difference defensively.
Hit a spell mid october where i wasnt scoring so many, switched the DLF to F9, as someone stated in this post already and havent looked back. Just hit the winter break, top of the league on goal difference from Juve whom I beat 2-0 away. Great tactic i'd say, as with every one just sometimes have to make small tweaks to suit your team
