The English Football League are planning to add a fifth division to their pyramid.
The Daily Star says the Football League wants to create an extra tier with 20 teams in each league for the start of the 2019-20 season.
A potential revamp of the structure – the first time since the creation of the Premier League in 1992 - would mean increasing the number of professional clubs from 92 to 100.
Football League bosses claim the expansion would halt fixture congestion and boost finances.
Clubs were yesterday notified about the plans and will vote on whether they support the changes in June 2017.
A 90 per cent approval rate, or 65 of the current 72 Football League clubs, is required to get the go-ahead.
Football League chief executive Shaun Harvey said: “There are clear benefits for everyone. Fixture congestion is one of the major issues facing the professional game in this country.
“It is about taking a step back to try to work out what is best for English football. We hope that the Football League taking this first step is the catalyst for future change."
