The defending champions take on Sriwijaya at Expo '70 Commemoration Park tomorrow before travelling to Indonesia in two weeks' time looking to maintain their 100% record in Group F.

And, with two victories already under their belts, Nishino knows that the next round is very much in his side's grasp.

"We want to win the upcoming two matches with Sriwijaya," said Nishino. "Then, we can move on to the remaining games in May with ease."

Nishino could ring the changes in his side after they failed to win either of their last two J.League matches.

He is unlikely to change much up front though, with Gamba having scored seven goals in their opening two matches.

The odds will be on them getting a sackful more against a Sriwijaya side who have leaked nine goals and whose goalkeeping problems continue to grow.

First-choice custodian and Indonesia international Ferry Rotishinu is still sidelined and stand-in Afriyanto broke his leg in the opening minutes of the 4-2 defeat by FC Seoul.

Coach Rahmad Darmawan will once again have to rely on Dede Sulaiman and he is hoping the defence will help the inexperienced youngster.

"We have practised several defensive formations and a number of possibilities as we know Gamba will be very difficult to beat at home," said Rahmad.

Elsewhere, Shandong Luneng take on South Korea's FC Seoul in what is set to be decisive in the race for second spot in the group.

Shandong recorded their first victory in the competition with a 5-0 thrashing of Sriwijaya but the Chinese champions followed that up with a 4-1 humiliation at the hands of Shanghai Shenhua in the league.

Coach Ljubisa Tumbakovic is confident they will emerge victorious tomorrow but admits his team are feeling the pressure to perform.

"We are looking forward to the game, although we have been psychologically affected by the match in the domestic league," he said.

Seoul are faced with the opposite scenario having lost their last Champions League tie 4-2 to Gamba but triumphed over Suwon Bluewings in the K-League at the weekend.

That result snapped a losing streak of three matches and they will be hoping to carry that momentum into tomorrow's game.

They will be boosted by the news that all their international players should be fit including Kim Chi-woo, Ki Sung-young and Lee Chung-young, who suffered an injury scare in the final minutes against Suwon but has passed a fitness test.
