Song is not a DM ,atm they need one..If they sell Song and replace him with M'Vila not a lot of damage would be caused to their first team imo,though ideally they would've wanted to get Sahin on loan too..

Azpilicueta will rotate with Ivanovic and i think Ivanovic could be used in some games at CB too..He wont be leaving,he's Chelsea's first choice RB with Azpilicueta his backup as of now.
