FRANKFURT, Germany -- Stefan Reisinger scored his third goal in three games as Fortuna Duesseldorf beat 10-man Eintracht Frankfurt 4-0 in a showdown between two promoted Bundesliga clubs on Friday.
Eintracht forward Karim Matmour was sent off in the 34th minute after a second yellow card, given for a professional foul. His team's downfall began four minutes later when Reisinger struck after a solo run through Frankfurt's makeshift, injury-hit defence. Matmour was back after serving a one-match suspension for another red card.
Oliver Fink doubled the lead in the 42nd with a fine shot from the edge of the area. Nando Rafael made it 3-0 in the 58th after a poor clearance by Eintracht's defence left him free at the far post. Axel Bellinghausen completed the win in the 85th.
Fortuna has won two of its last three, plus a 1-1 draw at defending champion Borussia Dortmund.
Eintracht's form has slumped after a strong start. The Frankfurt club lost a second straight match and has only one win in its last seven games. But it will remain in fifth place. Fortuna is 13th ahead of the weekend matches.
"I knew that it would be difficult for us because we were missing several players. Our defence never played in this line-up before," said coach Armin Veh, who has a tense relationship with the Duesseldorf club.
Veh called Matmour's dismissal unjustified. "It decided the match," Veh said.
Eintracht's defence included 17-year-old Marc-Oliver Kempf.
