Novak Djokovic will go into January's Australian Open looking for a third consecutive Grand Slam title and the Serbian should again be the man to beat in Melbourne.
The world number one has had some back issues though since his win at the US Open in September and there will be a host of players waiting to take his title, should he not be at his best come January.
Here are the five players who are worth watching out for in the betting
1) Andy Murray
The new world number three is more determined than ever to win a Grand Slam, after more disappointment in 2011. A final and three semis is not a bad run of results in the big four tournaments, but still a Slam alludes him.
Murray though has reached the final at Melbourne in the last two years and many feel the tournament is his best chance of Grand Slam success. His end of season form will also give him increased confidence going into the new year.
2) Rafael Nadal
You can bet the Spaniard will be working harder than anyone in the off season to close the gap on Djokovic. Nadal looked set to dominate the men's game before the Serbian’s rise in prominence and despite wining the French Open, 2011 will be classed as disappointing for him. Fans of online betting
should remember this.
Nadal will be back though and, should officials listen to his plea to lighten the schedule, expect him to come back firing in 2012.
3) Roger Federer
The Swiss legend looks to be nearing the end of his time as a Grand Slam contender, but if he has got one more title in him, this tournament could provide him with it.
Federer has won the Australian Open on four occasions and was runner-up in 2009, to Nadal. Many of the top players are caught on the hop at the early season events, but the 30-year-old always seems in top condition for the challenge Down Under.
4) Bernard Tomic
This teenager is a former Australian Open junior champion and has already made a big impact on the senior tour. Playing in front of his home crowd is likely to see him raise his game further and Tomic could be a real threat.
The 19-year-old reached the third round in Melbourne in 2011, knocking out the seeded Feliciano Lopez, before beaten by Nadal.
5) Jo-Wilfried Tsonga
The Frenchman can beat anyone on his day, as shown at Wimbledon this year, when he came back from two-sets down to defeat Roger Federer. Tsonga also has a decent record in Australia, reaching the final in 2008 and the last four in 2010.
The 26-year-old may feel it's now or never in his attempts to win a Grand Slam and the world number nine could yet spring a surprise come January.
