No Takashi Usami, no problem.

Gamba Osaka laid down the gauntlet to the J. League first-stage champions with a controlled 3-1 victory at Kashima Antlers as the second stage got underway on Saturday.

Kotaro Omori, Yasuyuki Konno and Kim Jungya scored for the 2014 Japanese treble winners, who sold Japan striker Usami after the first stage to Bundesliga club Augsburg last week.
