While attendances for Test match cricket in England remain strong, crowds for five-day cricket in other leading nations have been in decline for several years. As part of plans to boost Test match crowds around the world, the ICC has been looking at staging five-day games in a day-night format — something that currently happens only for one-dayers and Twenty20 internationals.

The ICC is also looking into creating a World Test Championship. Morgan, a former chairman of the England and Wales Cricket Board (ECB), said: "I'd be surprised if we don't see day-night Test cricket within the next two years, surprised and disappointed. In terms of each Test match having a context beyond bilateral series, real progress could be made soon," he added, saying there might be a "climax" although he didn't say how this would be achieved.

"We want to ensure Test match cricket is as popular around world as it is in this country (England). The ECB have little trouble in selling out the first four days of a Test."

Day-night matches were pioneered in Australia in the late 1970s during the "rebel" World Series Cricket contests bankrolled by media businessman Kerry Packer when 'Super Tests', with players wearing coloured clothing and using a white, rather than a traditional red, ball.

Morgan, who explained ICC wanted Tests played in as "close to white as possible", said. "Eighteen months ago, I wouldn't have been overly enthusiastic, thinking of the tradition and the records," the Welshman added. "But the way Test cricket has changed over 130-odd years, I see (day-nighters) as a very good reason for bringing the crowds out. At ICC, we regard Test cricket as the pinnacle of the game. It's the form of the game cricketers seek to play."
