South Africa's AB de Villiers: 'We were obsessed with goal to win'

South Africa captain AB de Villiers has claimed that he and his teammates were almost "obsessed" with their gameplan heading into today's World Cup quarter-final against Sri Lanka.

The Proteas claimed a nine-wicket victory at the Sydney Cricket Ground, sealing their first knockout win ever in the tournament.

JP Duminy took a hat-trick, while Imran Tahir snatched four wickets as Sri Lanka were bowled all out for 133.

"I'm very proud of what the guys achieved here today," BBC Sport quotes De Villiers as saying. "These knockout games are difficult games, difficult situations. We had a really good feeling when we came to the ground today. We were almost obsessed with our goal.

"We always knew JP would probably have to bowl 10 overs, so for him and Imran Tahir to come on in a crucial stage of the game and perform like that gives the spinners a lot of confidence."

South Africa reached their 134-run target inside 18 overs.
