Last time the Asia 3rd place gets to playoff against Oceania team, most of the time was New Zealand, so it was easy. But lately FIFA change the format and the Asia 3rd place gets to playoff against South America team, and most likely is very difficult due to their superiority.
when fifa did the playoff draw format
bo bian or suay depending on how u look at it
Asian side (winner of A3 vs B3) to take on Conmebol (as things stand, it's Colombia).
Concacaf (4th place team whh currently is Panama) vs Oceania Zone winner (likely New Zealand)
Asia traditionally don't do well agst Conmebol (take away the likes of Iran, Korea, Japan and Australia plus Saudi Arabia, pretty much AFC side not much of chance on paper)
last time when its in 2legged format, very tense and nail biting
given the covid restrictions, and to clear the backlog of fixtures
Oceania Zone playoff will be held as a mini group tournament in Qatar or something
Winner of the mini tournament will take on Concacaf 4th place team
also becos of covid, they scrap away the 2-legged format for the playoffs
do it one-off match in June in Qatar
