The AFC Champions League action returns to the continent this month as the 2018 edition gets underway shortly.
32 teams across the West and East Zones are set to battle it out for the coveted honour again. This year's edition is the 37th edition of Asia's premier club football tournament and the 16th under the current AFC Champions League title.
However, this year, there will not be a defending champion as holders Urawa Red Diamonds finished seventh in Japan's J1 League and failed to qualify for this year's edition.
The West Zone will have four groups (Group A, B, C and D) with four teams each, amounting to a total of 16 teams. The same applies for the East Zone as well (Groups E, F, G and H).
The teams will play each other twice in home and away format in the group and the top two teams will progress to the Round of 16.
The knockout stages will involve two-legged ties all the way to the final which is also held over two legs. However, one must note that only in the final will a West Zone team come face-to-face against an East Zone team.
