(CNN) -- Ireland reached the Super Eights stage of the World Twenty20 with a six-wicket win over Group A rivals Bangladesh at Nottingham's Trent Bridge after reaching their 138-run target with 10 balls to spare.
Ireland players jubilate on their way to reaching the Super Eights at the World Twenty20 cricket.
The O'Brien brothers, Kevin and Niall, hit 79 runs between them as Bangladesh exited the tournament after a second defeat in three days following a loss to defending champions India who also progress.
For Ireland, Monday's success was confirmation of their superiority over Test-playing rivals Bangladesh in a 74-run win at the World Cup in the Caribbean two years ago.
Niall O'Brien was named man of the match after smashing 40 off 25 balls and hopes Ireland can now surprise India in Wednesday's final group game.
"We believe in ourselves and we believe we can win every match so hopefully we can give India a game on Wednesday," he said at the post-match presentation ceremony.
Captain William Porterfield hailed the performance of O'Brien and his brother Kevin, who hit the winning boundary to take his score to 39 from 17 balls.
"They batted really well, it was a great effort the way they came in and took the game to the Bangladeshis," he said on Sky Sports 1.
"I thought the lads bowled really well and we'd have taken 137. I'm delighted with the great support here today and hopefully there'll be more for the Super Eights.
"Hopefully we can get a bit of World Cup fever going back home."
Bangladesh captain Mohammad Ashraful admitted his side were second best in all areas. "Ireland played very well," he said.
"We didn't bat well, we lost too many wickets, and they bowled and fielded really well. We thought we could still win but Ireland batted really well."
Bangladesh, who had to win to stay in the tournament, lost half their side by the 11th over with just 66 runs on the board.
Opener Tamim Iqbal was the only frontline batsman to offer any semblence of resistence, making 22 before he was run out.
