My team right now:
5-2-2-1
----------------------Pato-------------
-----------Lavezzi-----------Krasic--------
--------------Vidal------Natali (converted to CM)
Taiwo---Chiellini---Silva---Lucio---Abate
---------------------Buffon-----------------
I love this team. When I get more coins I'll buy Maicon. And some day, if I keep playing and find a way to get a ton of coins, sneijder to replace vidal.
The only problem right now is that there seems to be a glitch with this formation, where the LW is being a ST, that means every time there's a free kick or any stop in time, Pato and Lavezzi crash into eachother and collapse haha. It's pretty funny to see, but I don't mind too much because I'm winning a lot with this team.
