Federer setting sights on no. 3

There are a number of things Federer would like to achieve before ending the dismal year 2011.  First, he needs to defend the year-end title where he captured last year after defeating the then world no. 1 Rafael Nadal.  Seondly, he could climb back up to no. 3 and should serve as a consolation since it was very likely he was going to end up at no. 4 just a few weeks ago if not for Murray's recent mini slump.
