Johnston applauds the Irish support after the win over Bangladesh

Captain Trent Johnston says Ireland's World Cup campaign is not over, despite their famous victory over Bangladesh.

To finish seventh in the Super 8 on run rate, they must run Sri Lanka close on Wednesday then hope West Indies beat Bangladesh heavily the following day.

"We're not going to go out and celebrate as if we've won a World Cup because we haven't," said Johnston.

"We've got a big game still. We'll have a couple of quiet beers but take it easy, get on the plane and work hard."

Johnston took the final wicket in Barbados as Ireland claimed their second win over a Test-playing nation during their first World Cup.

"That was the best game of cricket since I've been involved with these guys over the last four years," said the Australian-born pace bowler.

"It was the best all-round performance we've had."

He sounded a note of caution to a side that had suffered four defeats in the Super 8, including a nine-wicket thrashing at the hands of Australia on Friday.

We're going to have to play better than this to be competitive against Sri Lanka Trent Johnston

"We've played one good game of cricket since beating Pakistan and we had two disappointing ones before this," he continued.

"We're going to have to play better than this to be competitive against Sri Lanka."

However, Johnston's joy was obvious at rebounding from what could have been a morale-sapping loss to the world champions.

The team performed a lap of honour, showing particular appreciation for the estimated 300 fans who were in Jamaica for the group games and returned for the Barbados leg of the Super 8.

"A lot of people spent a lot of money to come over and watch us play two games of cricket," Johnston added.

"It was a huge game against Australia and we were nothing short of disappointing so we had to turn that around quick smart.
