There is a common fact that normal team has to has a 6 attacking men if going to play 4 3 3. So every position in attack needs two contenders. We have Vucinic on the left, Matri CF, and Pepe RF, Quag who I guess considered as a CF and Boriello who is also CF. On the flanks there is a lack of quality performers. So Everything clear =D Suarez\Lavezzi\Jovetic as a winger and Cavani\Rvp\Higuain as a CF. And dump Boriello and Matri\Quag or use Quag as back up for winger position.
