Kruno Lovrak scored a hat-trick as South Korea's Jeonbuk Motors eased to a 4-1 victory over Indonesia's Persipura.

Kim Seung-yong's 15th minute penalty opened the scoring for the 2007 champions before Lovrak was introduced midway through the first half.

And just two minutes later Lovrak doubled Jeonbuk's lead when he lost his marker and fired home.

Goalkeeper Kwon Sun-tae denied Persipura duo Stevie Bonsapia and Gerard Pangkali at the end of the first half before the home side made an encouraging start after the break.

But Persipura's lack of concentration proved crucial as Lovrak capped off a swift counter-attack six minutes after the hour mark.

Ian Kabes curled home an impressive consolation for the hosts a minute later, but with nine minutes remaining Lovrak completed his hat-trick to seal the win with a close range finish.

In Kashima, J. League champions Kashima Antlers also got their Group F campaign off to a winning start with a 1-0 win over Chinese Super League side Changchun Yatai.

Former Japan international Koji Nakata headed home Takuya Nozawa's free-kick three minutes before half-time at Kashima Soccer Stadium to hand the three-time J. League champions all three points.
