Although Roger Federer has been beaten by Andy murrayy in the semi final of Abu Dhabi semi final but I think Federer must over look it and start fresh .
Federer was also last beaten by Andy Murray in the Tennis masters cup but he has never been able to beat federer in grand slams yet.
Federer must keep himself fit and quick for this year,we know there comes one bad year in every player’s life but failure in this year would severely rank his ability to fight back.
