Britain's head coach Jon Royce called for changes to the rules following his team's 3-2 victory over South Africa.

Pointing out that his side scored more goals in Monday's match than Spain have scored in the whole tournament, Royce believes play has become too negative.

He said: "With no offside, the game is very negative. Players go backwards and sideways and attack down the edges.

"Spain have only scored twice in the tournament. I have a number of suggestions and although I have raised points before in England, it appears nothing has been done."

Jane Smith's penalty corner goal helped Britain's women secure victory at the State Hockey Centre.

Smith's flick from Britain's third set piece in the 38th minute turned out to be the matchwinner and secured a place in Wednesday's play-off to decide seventh or eighth spot.

Scottish forward Rhona Simpson fired Britain ahead in the third minute with her first goal in the competition after Smith had made a fine run along the byline.

But the Springboks were level within three minutes after Alison Dare deflected in Kerry Bee's free hit.

Mel Clewlow restored Britain's lead when she hammered in a penalty corner but Simpson squandered several superb chances to put the game beyond South Africa's reach.

Pietie Coetzee made Britain pay with an equaliser, beating Kath Johnson and Denise Marston-Smith at the edge of the circle before firing in an unstoppable shot.

In a lacklustre second half - both teams showing the effects of their fifth game in the event - Smith struck three minutes after the restart to restore Britain's lead.

Royce admitted he was pleased with the win against South Africa, adding: "Overall, on the balance of play, we deserved to win. But we went a bit wobbly in the second half and should have played better on the counter attack when the Springboks were attacking."

Captain Pauline Stott, who sat out the second half, said she wasn't disappointed to have been substituted.

"I can't complain because we have a 16-member squad and everyone plays. We had to come out strongly and win and we made a great start. At least winning means we don't have to get up at 4.30am to play in an early game next up."

Royce said he didn't mind who they faced next - Germany or Korea. He added: "We'll take who comes but we definitely want to win to ensure seventh place. Our players have dedicated 152 days, and four to five hours a day training in the build-up and are devastated to miss out on a medal. The next best thing is to win these matches."
