The Australian side opened the scoring through Kerem Bulut in the 12th minute before Go Yo-han got the equaliser for the visitors in the 72nd minute after an assist from Brazilian striker Everton Santos.
The visitors played very cautiously during the first-half hardly testing keeper Ante Covic in goal.
The opening goal came about when Iacopo La Rocca crossed the ball in the area towards Labinot Haliti, the ball fell to Bulut, who scored with a shot from about 12-metres out to give his side a 1-0 lead in the 12th minute.
More goals should have come for the home side as Haliti shot wide from a good position and then missed again after getting a decent Yoyiro Takahagi cross in the area to shoot wide.
During the second half FC Seoul were a different side and attacked relentlessly peppering the Wanderers goal, including hitting the crossbar with a Mauricio Molina shot.
They were rewarded in the 72nd minute when Cha Du Ri sent through a quality pass to Santos who in turn supplied Go Yo-han who scored with a tap in to make the score 1-1.
Wanderers’ keeper Covic was involved in controversy late in the game when he appeared to fall across the goalline holding the ball after making a save, but was never penalised and got away with what looked like a goal.
In the end the match ended 1-1.
The result sees Wanderers on five points in second place on the table behind Chinese side Guangzhou Evergrange on nine points.
FC Seoul are third on goal difference with five points, ahead of bottom placed Kashima Antlers of Japan on three points.
