ANDY MURRAY has hit out at a potential loophole which could see him miss out on the end-of-season ATP Finals in London.

The Scot begins his bid for the Austrian Open today and hopes a win will secure his place at the London event next month.

But a rule change gives automatic entry to a Grand Slam winner no matter how many points they accumulate in the season.

And that has opened the door for US Open winner Marin Cilic to take part at the possible expense of Murray.

The British No.1 said: "You would hope that the players who would get in would be those who accumulate the most points across the whole year on the ATP tour."
