Holger Osieck's men maintained their superiority over the side they defeated to win the Asian Champions League thanks to goals from Yuichi Nagai and Washington, as well as an own goal from Hadi Aghily, leaving Japan's best supported club to meet Milan in a highly-anticipated clash in Yokohama on Thursday.

Nagai gave Urawa a deserved lead 13 minutes before half-time when he struck from inside the six yard box after an inch perfect cross from Takahito Soma.

Washington then doubled his side's advantage nine minutes after the restart with a perfectly executed finish.

Aghily compounded Sepahan's misery 20 minutes from time when he headed into his own goal after Nagai had directed Soma's cross into the defender's path before Mahmoud Karimi claimed an 80th-minute consolation for the Iranian visitors.

The win was no more than Urawa deserved after controlling most of the game and the former J.League champions should have led by more than the one goal they managed in the opening 45 minutes.

Washington went close to giving Reds the lead after just 11 minutes when he almost capped a fine move involving Keita Suzuki and Marcus Tulio Tanaka, only for the Brazilian's attempt to curl the ball into the top corner to miss by the narrowest of margins.

Suzuki was next to try his luck in the 21st minute when he stole possession from Abdulwahab Abuhail only for the Urawa captain's shot to trundle tamely through to Mohammad Savari.

Washington against caused consternation in the Sepahan defence four minutes later when he picked up Yuki Abe's pass before beating two defenders and firing his shot just over the bar.

Sepahan offered very little in attack in the 27 minutes before Emad Mohammed almost unlocked the Reds defence.

The Iraqi international deftly controlled a flighted ball into the box by his compatriot Abuhail only for his low cross to sear across the face of the Urawa goal and behind the on-rushing Kabir Bello.

That near miss was a warning to Reds and in the 30th minute they should have taken the lead.

Washington laid the ball out to the impressive Soma and his cross was directed into the path of Makoto Hasebe by Nagai, only for Hasebe to fire over the bar with the goal at his mercy.

Fortunately for Urawa, Nagai was on hand to show Hasebe how to finish less than two minutes later. Again Soma sprinted down the left before sliding his cross through the Sepahan defence to leave Nagai with the simplest of finishes.

Two minutes into the second half Sepahan came within inches of pulling level when Abuhail's right-foot drive was deflected onto the Reds crossbar thanks to Abe's desperate lunge.

Seven minutes later the game was all but over as a contest thanks to Washington's brilliant finish, the former Atletico Paranaense striker latching on to Abe's pass before rounding Savari and hammering home from the tightest of angles.

Aghily's 70th-minute header past his own goalkeeper allowed Reds to take their foot off the gas although Karimi did give Sepahan something to smile about when he outstripped Tulio before slotting past Ryota Tsuzuki.
