FC Seoul boss Senol Gunes was thrilled with his side’s 5-1 victory over Sriwijaya on Tuesday but brought a touch of realism about their chances of reaching the knockout phase.

A Dejan Damjanovic hat-trick and Sim Woo-yeon’s brace gave the Korea Republic side a convincing triumph over the lowly Indonesians after they were stunned by Keith Gumbs’ 61st minute equaliser

Three goals in quick succession won the game for the hosts and puts Seoul level on points with Shandong Luneng, who entertain group leaders Gamba Osaka on Wednesday.

The defeat leaves Sriwijaya with just one remaining game in which to pick up their first point of the competition.

Shandong Luneng coach Ljubisa Tumbakovic insists nothing will stop his side from securing their place in the last 16 despite the Chinese side losing 1-0 to 10-man Gamba Osaka on Wednesday.

Brazilian striker Leandro scored the winner two minutes before the hour mark to hand the defending champions their fifth win in a row after influential playmaker Yasuhito Endo was sent off before the break.

Shandong have seven points along with FC Seoul, but can take second place in Group F if they defeat Sriwijaya away on May 20.
