We at least need to decide what to do with DC and Giovinco first.
They need to play a role and their part along with the coming additions will be essential to our plan.
Right now w have an abundance of quality players in some areas and a lack of areas in some others, this might change in the future, our flanks are very weak at the moment and the last system we should play, is the one we do, therefore i think its highly unlikely that CR would consider another system anyway...
The 4-2-3-1 is out question with the amount of quality/expensive forwards we currently have and the ones who are bound to obtain , regardless of our needs...
