This high tempo tactic is designed to create a large number of clear-cut-chances. The absence of a striker causes the opposition defence to push up, or risk giving your AMs chance to turn. This creates a lot of space in behind. Your attacking midfielders will often find themselves 3v2 in attack. Should the opposition full-backs come narrower to help the centre backs, room will be created for your own full-backs to attack (Last season my second choice left-back scored three hat-tricks)
I've been using it in the lower leagues with some success:
and some very high scores (a few 8-0 scorelines)
As with all tactics, it will work best once your whole team is fully trained in the formation, and I tend to leave the training on attacking movement once this is achieved.
I've scored a fair few from corners too, just make sure your best heading CB (Height, Jumping, Heading, Aggression, Bravery) is in the left slot.
It will be interesting to see how it works for people in the top leagues, and if you're worried about finding teams with AMCs...
(Shadow strikers in lower case, Trequartistas in CAPS)
Man U: Rooney MATA Kagawa
Chelsea: Hazard OSCAR Willian
Liverpool: Suarez COUTINHO Sterling
Arsenal and Tottenham are mostly AMCs anyway...
Man City: Aguero SILVA Nasri
The only thing I would say, is that it's not a possession orientated or high pressure system, so if you're chasing the game with 10 minutes left, you might not get the ball back...
