We need protection for the back four - the only player that Bobby has highlighted on numerous occassions that we need to fill this area in - De Rossi.
We should not fuck around now in this January window and go and get the targets required to move the squad forward that Bobby knows he needs, starting with De Rossi.
Having him sat infront of the back four will allow Yaya the freedom to revert back to attacking play with Silva. Yaya would have the confidence to know that a world class player is in position to allow him to burst forward.
