(CNN) -- Leandro Benitez scored both goals as Copa Libertadores winners Estudiantes de La Plata beat Pohang Steelers 2-1 in Abu Dhabi on Tuesday to book their place in the Club World Cup final.
The Argentine side will now face either Barcelona or Atlante on Saturday after a turbulent second half at the Mohammed Bin Zayed Stadium saw the South Korean side finish with just eight players.
Benitez opened the scoring with a free-kick on the stroke of half-time, curling home a 25-yard strike that deceived goalkeeper Shin Hwa Yong.
The same player doubled his account eight minutes after the break before things took a turn for the worse for the Asian champions when Hwang Jae-Won received a second yellow card three minutes after the goal.
Brazilian striker Denilson made light of that loss to give his side a chance with a 71st-minute strike -- but within six minutes the Korean side had lost another two players.
Kim Jae-Sung was first to go moments after the goal and keeper Shin followed five minutes later to leave Pohang with eight men.
