Striker Rob Moore scored a last-minute winner against India to ensure Great Britain retained their unbeaten record in the Olympic qualifiers in Chile.

Britain fell behind early on after VR Raghunath converted a penalty corner, but India were then reduced to 10 men after Vickram Kanth got a yellow card.

Richard Mantell pulled GB level, with Jonty Clarke finishing well on 46 minutes to make it 2-1.

Raghunath equalised for India, before Moore netted from a free hit late on.

With one match to go before the final GB are three points clear at the top of the table.

"This was a feisty encounter, but our boys kept their discipline and got on with the game and we're obviously pleased with the result," said GB team manager Pete Nicholson.

Having thrashed Mexico 11-0 in their first game, GB then put eight past Russia without reply, before beating hosts Chile 4-1 in their third game.

Nicholson's side, who are now all but assured of place in Sunday's final, next play Austria in their last group game.

If GB fail to qualify, it would be the first time they have missed the Olympics since the 1980 Games in Moscow.

The Chile event is the second of three qualifying events for the 12-team Olympic hockey competition.

New Zealand beat Argentina in the final of the first tournament last month, with the third event in Japan next month.

China, Netherlands, South Korea, Canada, South Africa, Spain, Belarus, Pakistan and Australia have also qualified.
