David Moyes believes the failure of the breakaway European Super League (ESL) provides an opportunity to consider a unified British competition instead.
However, Moyes believes league reform is still needed and suggested a Premier League II - which includes Rangers and Celtic - could be an option.
"Change is needed in some way," said the West Ham boss.
"I think the Premier League has a brilliant product, I really do, but at the top clubs you're talking about too many games, so could we have Premier League I and Premier League II?
"Could we have a situation where we do invite Rangers and Celtic to Premier League II?
