Urawa Reds boss Mihailo Petrovic insists he will be taking nothing for granted when the J-League leaders take on Western Sydney Wanderers at home on Wednesday in the Asian Champions League, despite looking a strong bet to get the result they need to book a spot in the knockout phase.

Reds hammered Sydney 4-0 away in their opening game of the group phase back in February and with two games left to play, they only need a draw against the Australian A-League side to advance to the two-leg round of 16.

Reds top the Group F standings with nine points. China's Shanghai SIPG also have nine points while South Korea's FC Seoul and Sydney have three points each.

Speaking on the eve of the match at Saitama Stadium, Petrovic said, "There is not that much difference (in quality) between the teams and I think you could even say this is a group of death."

"Western Sydney have played better away than they have at home and tomorrow's game will be far from easy. But my players have prepared well and will pull together and try and win the game."

Reds goalkeeper Shusaku Nishikawa said, "We are ready for a tough match. As a goalkeeper all I can do is try and stop goals from going in and show my quality. If I can do that hopefully it will contribute to the team getting a win. We are determined to qualify for the next round."

Although second place will be good enough to see Reds advance, Petrovic wants to go through as Group F winners.

"We want to qualify as group winners. Last year we went through in second place and this time we want to get to the next stage in first."

The winners of Group F face the runners-up of Group H, which features Reds bitter J-League rivals Gamba Osaka.

Gamba are currently bottom of Group H on three points but only one point behind second-place A-League side Adelaide United, who they face at home later on Tuesday.

The Group F runners-up will take on China's Jiangsu, who have already secured top spot in Group H.

Sydney lost their last game 3-2 at home to Seoul, having beaten the South Koreans by the same scoreline away on March 15.

Reds, the 2007 ACL champions, lost in the round of 16 last year to Seoul, going out 7-6 on penalties after the tie finished 3-3 on aggregate.

In Tuesday's other match involving a J-League team, Kawasaki Frontale are away to South Korea's Suwon Bluewings in Group G.

Reigning J-League champions Kashima Antlers face South Korea's Ulsan Hyundai in Group E on Wednesday.
