This tactic is inspired by 2006/2007 Carlo Ancelotti's Christmas Tree.
After the shocking departure of Shevchenko, Ancelotti redesigned his team with just one forward (Inzaghi), supported by two advanced playmakers and a muscolar midfield.
As a metter of fact, Ambrosini and Gattuso had the responsability to give balance and solidity to Ac Milan, which had a strong attacking propensity based on creativity, fantasy
and high technical skills.
This tactic is most suitable for big teams, with an high techical rate and skilled players.
You will see a funny ,bubbling and unpredictable offensive playing, altough your defense may concede some chanches to the opponents.
I found sometime little difficulties with small and closed teams, especially away from home, also for this it's important to have high technical skilled players,
that can resolve a match with an individual action
