With Andy Murray yet to drop a set in this years Australian Open bookmakers are starting to become concerned that the Scot may finally clinch his first major title .
Murray has been in sensational form in Melbourne and now faces Alexandr Dolgopolov in the quarter final with the prospect of a semi-final against Rafael Nadal .
Murray is strongly fancied to beat the unseeded Dolgopolov who suprisingly beat Robin Soderling in five sets to make the quarter finals . Murray is taking nothing for granted and said after his straight sets victory over Jurgen Melzer :"It's been a very good start, but it's going to get much tougher."
Nadal set up his quarter final with David Ferrer with a straight sets win over Marin Cilic and the Spaniard is attempting to become the first man since Rod Laver in 1969 to hold all 4 grand slams at the same time .
Bookmakers expect Andy Murray to win his quarter final in straight sets with the best odds available for a 3-0 scoreline the 4/6 quoted by Ladbrokes .
William Hill spokesman Rupert Adams is quoting odds on what stage Murray will be eliminated from the tournament and said "Murray has never looked sharper but Rafa is on the horizon so punters have not come in too hard just yet."
William Hill quote Murray at odds of 4/5 to be eliminated at the semi-final stage and 4/1 to lose in the Final .
Irish bookmaker Boylesports are one of the few bookies who still offer odds of 5/1 for Murray to win the Australian Open and land his first grand slam .
