SELANGOR coach Katsuhito Kinoshi said his side must grow stronger and sharper after conceding a crushing stoppage-time equaliser in their 1-1 draw with Buriram United in the Asean Club Championship (ACC) Group A opener yesterday.

The Red Giants were seconds away from a statement victory at Buriram Stadium after Brazilian striker Chrigor Moraes fired them ahead in the 38th minute.

Still, Austrian midfielder Peter Zulj rose higher to head home in stoppage time (90+6), denying Selangor all three points.

"Yeah, first half, I'm so satisfied with the first half," said Japanese Kinoshi.

"But now I realise I have to have training for the next match for 130 minutes, maybe 150 minutes, something like that. We need to implement stronger and tougher training for our upcoming matches."

Kinoshi said that despite the gut-wrenching finale, his players should not be disheartened.

"Until the 95th minute, we were leading. So this is something we must have confidence in and be proud of," he said.

"But Buriram let me know we are not good enough yet to win against a team like them. We must improve."

Selangor had looked organised and dangerous on the break in the first half, with Zach Clough's free kick going close before Chrigor smashed home Noor Al Rawabdeh's clever through ball.

Buriram dominated possession throughout but were frustrated by Selangor goalkeeper Kalamullah Al Hafiz, who pulled off a string of saves to deny Guilherme Bissoli and Suphanat Mueanta.

Robert Zulj also struck the post before his brother, Peter, finally made the breakthrough with virtually the last play of the match.
