Kawasaki Frontale came from behind to take a slender lead into next week's Asian Champions League quarterfinal second leg after beating Nagoya Grampus 2-1 in Wednesday's opening encounter.

Josh Kennedy put Grampus ahead with a header in the 28th minute, giving his side a precious away goal with Frontale hosting the game at Tokyo's National Stadium.

But a piece of crafty opportunism from Kengo Nakamura brought Kawasaki level on the hour mark, three minutes before Juninho completed the turnaround by pouncing on a rebound from a Hiroyuki Taniguchi header.
