Indeed, the Rangers head coach believes supporters may tire of the same old fixtures and, considering the need to keep a product 'fresh,' would be more enticed by Celtic and the Gers moving south of the border.
Warburton is quoted as telling reporters: "I am sure you will get to the stage sooner or later where team X versus team Y hasn't got the same appeal to the average fan in the street, whereas Manchester United versus Rangers, Celtic versus Arsenal etcetera, it is new, it is fresh, it is another level of excitement.
"I am sure any product is always looking to keep it fresh. If you ask any people down south they recognise the potential of clubs such as Celtic and Rangers. There is no doubt about that."
Warburton and many at Celtic appear to be on the same wavelength on this one.
May fans in Scotland have grown tired of the suggestions, however, and feel Rangers and the Bhoys will always be bound to playing solely north of the border.
The Rangers boss did also outline some stumbling blocks, of course, and the biggest one to take into consideration is where exactly the Gers and Celtic will start off if they began to play English teams?
While both the Hoops and the Ibrox outfit could outperform many rivals long term due to the income they will get from fans as well as TV money, they wouldn't have any given right to start off in the Premier League straight away.
