Novak Djokovic faces a stiff task to repeat his mesmerising 2011 season and as a result you can get some great value odds on the Serb ending 2012 as world number one.
In the current era it takes at least 2 Grand Slam titles to finish the calendar year as world number one and so Djokovic can ill afford to slack off if he's to maintain his perch at the top of the rankings.
Unibet are offering some great value odds with Djokovic at 2.10 to finish the year as world number one.
The Serb is also 2.90 to defend his Australian Open title in January with in-form Roger Federer at 4.00, great value for the four-time champion.
If you fancy your long shots, Juan Martin Del Potro is 13.00 to win in Melbourne, worth a flutter after his stunning displays during the Davis Cup final. Two-time finalist Andy Murray is 7.50 to break that Grand Slam duck down under and 2.48 to finally claim that elusive first major title in 2012.
As for the WTA, well Serena Williams is favourite for the Aussie Open at 3.65 with defending champion Kim Clijsters an enticing 15.00 to go all the way, decent value given her performance against Caroline Wozniacki in a recent exhibition.
Petra Kvitova fans are advised to hold your fire just yet. The Czech may be second favourite at 4.50 but she's never been past the quarters at a hard-court slam.
