Awful defending from Marin Vidosevic allowed Padang striker Edward Junior Wilson to open the scoring at the Jalan Besar Stadium in the 40th minute, before the Liberian striker netted his second shortly after the hour mark after Titus Bonai had won possession from Shukor Zailan and played the ball into his path.
Both goals could perhaps have been avoided with more decisive defending but, in the end, the result was enough to end any hopes the Warriors had of finishing inside the top two in Group E and qualify for the Round of 16.
Speaking after the game, Selvaraj agreed with that assessment but abstained from being overly critical of his players.
"It's true that we paid for our individual mistakes," he said. "In the past few games we have been giving away soft goals.
"Things might have been different if we had kept things simple but all I can do is remind them to keep things simple at the crucial moment.
"Perhaps frustration got to the players. We missed a lot of chances and I feel bad for my defence - they worked very hard and must have been frustrated we weren't converting our chances."
Warriors' elimination followed that of Great Eastern-YEO's S.League champions Tampines Rovers a day earlier, meaning there will be no Singaporean representative in the knockout stage.
However, Selvaraj refuted suggestions the S.League sides are no longer to compete at this level and believes things could have been very different had his players been sharper in front of goal.
"Comparing both matches [against Semen Padang], we created more chances over here," he added. "I think we [Singaporean teams] are still up there with the rest.
"We just need more confidence. If Sufian [Anuar], Kari [Mislav Karoglan] and even [Tatsuro] Inui had been sharper, we could have been three goals up in the first 20 minutes.
"I would say our local teams are still good enough."
Although Semen Padang coach Jafri Sastra was pleased that his side were able to wrap up top spot with Wednesday's win, he insists they will not be taking it easy in next week's final Group E game at home to Churchill Brothers.
"Even though we have already qualified, we will still focus on the next match to maintain our unbeaten record in this group," he said.
"We aren't surprised by how well we've done because we had special preparation from the first match till now, after we found out we were participating in the AFC Cup.
"We already had the target of getting past the group stage."
Kabau Sirah will meet the runners-up of Group G in the Round of 16 and it could be anyone from Malaysian treble winners Kelantan, Vietnam's SHB Da Nang or Maziya of Maldives.
Jafri is not concerned by which team his side get us last-16 opponents, and insists they will worry about that when the time comes.
"The team is ready - whoever we face, it is no problem," he added.
"When we get back to Padang, we will start thinking more about our preparations for the next stage."
In Wednesday's other Group E clash, Kitchee wrapped up their progress with an impressive 4-0 away win over Churchill Brothers.
