FC Tokyo opened their Asian Champions League campaign on Tuesday with a 1-1 draw against Group F opponents Ulsan Hyundai after an own goal from Adailton canceled out Diego Oliveira's opener.

Seeking their first win in three meetings with the South Korean club, Kenta Hasegawa's men looked on track when Oliveira scored on a breakaway in the 64th minute at a sparsely populated Ulsan Munsu Football Stadium.

After running onto a through ball from compatriot Leandro, the Brazilian forward angled a low shot from the left of the area past Ulsan keeper Jo Su-huk and inside the opposite post.
