Auckland: Pakistan thumped South Korea 6-2 to post their first win of the Champions Trophy on Thursday, while Germany scored a last-gasp winner against Great Britain.

Pakistan came from behind to snap a three-game losing streak at the last major men's tournament before the London Olympics, with captain Muhammad Imran and Abdul Khan both notching a brace.

Imran proved the inspiration for a Pakistan fightback after Lee Nam-Yong's seventh minute goal gave Korea the lead, with the skipper converting a penalty corner after 15 minutes to put the Green Shirts on the board.

Khan followed up with a field goal one minute later and from there Pakistan looked assured, holding their nerve when Korea equalised and sealing the win with a four-goal burst in the final 10 minutes.

Imran said Pakistan, making their first appearance at the tournament since 2007, had finally put together a consistent performance after patchy displays in the opening rounds, including a 6-1 loss to defending champions Australia.

"For the whole match we played very well," he said.

Manager Khawaja Junaid was pleased with the way his team bounced back from the confidence-sapping loss to the Kookaburras.

He said that the Green Shirts, whose early losses mean they are out of medal contention in Auckland, still lagged behind the world's top teams but the gap was closing.

"I think that was the turning point for our team," he said.
