Spend Roman's Money !!!

(In light of speculation surrounding Chelsea and the apparent "monies" Roman Abramovich has to spend in the January transfer window)
You are now Carlo Ancelotti. You have just had a meeting with Roman Abramovich and he has confirmed that he understands the situation with the squad and injuries and is willing to spend "Whatever it takes" to make sure Chelsea remain strong throughout the full squad to cope with possible injuries and suspensions.

So you have an open chequebook for January. Bearing in mind Champions League registrations etc and to be aware of who could play and who is unable to because they have already played for someone else the questions I would like you the fans to answer are:

What players would you bring in, allow to leave either permanently or on loan and give your reasons!?
