Wimbledon champion Andy Murray has lowered expectations ahead of his comeback by admitting that it could be difficult to add to his Grand Slam haul.
The Scot ended the 77-year wait for a British winner at SW19 last summer, having opened his major account by triumphing at the US Open in 2012.
Murray is poised to make his return from a three-month injury layoff at the Mubadala World Tennis Championship on Boxing Day, which will act as his warm-up for January's Australian Open.
He has stressed that will try everything in his power to taste success at the highest level again, but has confessed that the standard of his rivals means that there is no guarantees.
He told Sky Sports News: "I want to try and win as much as I can, I lost enough times in big matches to not want to do that.
"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."
Murray beat world number one Novak Djokovic in both of his Grand Slam final wins.
