Murray happy to be a contender

Andy Murray could beat Roger Federer on Thursday and crash out of the ATP World Tour Finals or lose and go through to the semifinals - such is the conundrum he faces.

However, the 27-year-old home favorite is glad just to still be in contention after Tuesday's 6-3, 7-5 triumph over big-serving Canadian Milos Raonic.

That victory, following his loss to Kei Nishikori in Group B on Sunday, means all scenarios are in play going into the final round-robin matches, although a straight-sets win for world No 6 Murray would leave him in good shape.
