China crush Guam, Aussies beat Nepal in Qatar qualifier

China struggled to keep up the pressure and would have gone scoreless in the second half without a sudden strike by Brazil-born Elkeson, who in August became the first player without Chinese heritage to be named in the national squad.

Yang found his first in the sixth minute off a cross from Wang Gang but Guam looked like levelling soon after with some gaping holes in the hosts' defence.

Winger Wu Lei's feint around Travis Nicklaw into goal from the penalty line checked the brief burst of momentum from the visitors and Yang's second moments later kept the hosts on the front foot for the rest of the half.

Yang made his fourth at the 31st minute and shook off a tumble soon after that saw a yellow card for Nicklaw, while Yu Xi's header brought China to six.

With the other scorers benched after the break, Yang's best shot at a fifth was flagged offside.

Elkeson stepped up in the 75th minute but missed his chance at matching the double he made on debut against the Maldives last month in the final shortly before the whistle.

- Maclaren hat-trick -

Meanwhile Jamie Maclaren made a hat-trick in Australia's 5-0 thrashing of Nepal during Thursday's World Cup qualifier in Canberra.

The Socceroos missed several opportunities against their 161st-ranked visitors but maintained a tight defence and dominated possession through the match.

Their opponents were flagging by half-time, with a dogged showing by keeper Kiran Chemjong avoiding a bigger blowout.

"We created a lot of chances, but we got a bit more ruthless when it counts," said Australia coach Graham Arnold after his side's biggest home win in three years. "Overall, I'm very happy."

Melbourne City's Maclaren opened scoring in the sixth minute when Chemjong lost his grip on a drive from the top of the box.

He doubled the lead in the 18th with a header off Rhyan Grant.

International debutant Harry Souttar followed five minutes later with his own nod into goal, but a potential fourth by Mathew Leckie seconds before the break was controversially ruled offside.

By then the Aussies had made 16 shots on goal against a solitary attempt by the visitors -- a 44th minute Hail Mary from Abhishek Rijal from near the half-way line.

The visitors rallied in the second half but notched an own goal after failing to deflect Souttar in minute 59.

Late substitutes Ajdin Hrustic and Awer Mabil kept up the pressure but could not capitalise on their attempts before Maclaren made his third in the closing moments.

"(It's) my proudest moment in a football jersey," he told Fox Sports after the match, while conceding that his side squandered a few easy opportunities through the match.

"End of the day we scored five... but looking back we could've scored more," he said.

Striker Kim Shin-wook scored four in South Korea's 8-0 drubbing of Sri Lanka while Japan triumphed 6-0 against Mongolia in Thursday's other second round group matches.
