Bangladesh head coach Thomas Dooley conceded his side were undone by a class gap after their FIFA ASEAN Cup 2026 opener ended in a 3-0 defeat to Malaysia at the Gelora Bung Karno Stadium on Friday.

Goals from Arif Aiman (18', 38') and debutant Bergson Gustavo (53') sealed the win for Malaysia, ranked 136th in the world against Bangladesh, ranked 181st.

"It's obviously not the dream that we had today, but also a more realistic game where we can see the difference between us and them is in accuracy, technical, tactical," Dooley said at the post-match press conference.

"There's a reason why they are in the rankings way up than Bangladesh and our team…. We made a lot of mistakes in passing and accuracy, so we gave them a little bit of space. They could play in front of our goal," he said.

"You could see the quality of the players they have up front — it's just a different level," Dooley said, pointing to Malaysia's attacking trio as the difference-makers.

He defended his backline, saying the defence "did a good job" overall despite conceding three, though tired legs told as the game wore on.

"We tried to play out of the back, and in the end you could see the players are tired and cramping up, making more mistakes," he added.

Dooley was measured on the result itself, insisting he did not expect Bangladesh to trouble Malaysia given the gap in quality between the two sides.

"I don't expect to beat Malaysia in this tournament 2-0, 3-0 or something like that. We played a team that is way ahead of us, and that's the difference between them and us," he said.

Debutants Farhaan Ali Wahid, Shuki Itofusa and Zidane Yousuf all featured, with Dooley praising both Farhaan and Itofusa despite the heavy defeat.

"This game was not so for Farhaan because he's more a player who needs to be in front of goal. But he trained well and played well," Dooley said.

"With Shuki, we got a little more offensive power. He could give us some air in the second half and make it more dangerous up front," he added.

Hamza Choudhury had Bangladesh's best chance, forcing a save and a follow-up block in the 76th minute.

Hamza tried to cover every blade of grass in the match, often trying to pry the ball off opposition at the midfield, pressing forward at goalmouth and rushing back to strengthen the defence.

Dooley pointed out how crucial the Sheffield United player is for Bangladesh in every position.

“We need Hamza in the back, we need him in the midfield offense, midfield defense, and we could also need Hamza in a forward position,” he said.

Dooley also backed goalkeeper Mehedi Hasan Srabon, who kept out a fierce early Malaysia effort, saying the scoreline was not down to his shot-stopper.

"He had some great saves. It's definitely not the goalkeeper's fault that we got three goals today."

The coach noted that several of his players arrived undercooked, having gone without club football since Bangladesh's last outing against San Marino.

"Some of the players haven't trained since the last game in San Marino. If you're not in a league and playing against Malaysia, who are in a league and playing international football, it's very difficult," he said.

Looking ahead, Dooley said his side would review the footage before facing Singapore, with Indonesia to follow in Group A.

"We need to learn, analyze the video, show every single play, and learn from it. We don't have a lot of time before the next game.

"Overall, I'm okay with the game, and we're here to learn," Dooley concluded.

Bangladesh's next Group A fixture is against Singapore on September 28.
