Andy Murray admits it will be tough to add to his haul of two grand slam titles, but it will not be for the want of trying.
The 26-year-old Scot bounced back from losing his first four grand slam finals to capture the US Open title in 2012 before winning Wimbledon earlier this year.
He missed the end of last season after undergoing back surgery but - after some hard training in Florida - he is set to return to action in Abu Dhabi on Boxing Day as he prepares for next month's Australian Open.
"I want to try and win as much as I can, I lost enough times in big matches to not want to do that," Murray told Sky Sports.
"I don't want to lose four slam finals in a row again; that was horrible.
"But I also know how hard it is to win those tournaments. It may never happen again, I might not win another one but I just want to give myself the best chance to do that and that's why we do the work over here and train and prepare as best as we can.
"Hopefully I'll give myself an opportunity to win another one."
