Kota Mizunuma scored twice as FC Tokyo opened the Round of 16 in the Asian Champions League with a 2-1 win over Shanghai SIPG on Tuesday.
Mizunuma opened the scoring with a free kick just before half-time and added his second with a well-timed volley in the 65th minute after striker Wu Lei had equalised for the Chinese Super League club.
Leonardo scored a vital away goal for Jeonbuk, helping the K-League club hold Melbourne Victory to a 1-1 draw and a slender advantage in the return leg next week on home soil.

Matthieu Delpierre brought down Han Kyo-won on the edge of the area and Leonardo curled the resulting free kick past Victory goalkeeper Lawrence Thomas.
