Would be dead set against either Rangers or Celtic ever being allowed into any English division for plenty of reasons.
Firstly it would inevitably bring with it all the sectarian shite that follows both clubs to England and no doubt the violence that accompanies it. Seem to remember it was not that long ago that one of them played in Manchester and virtually trashed the place. Think every Police Chief up and down the country would object to it too.
Secondly for them to be accomedated in any division it would require two English teams to be relegated through no fault of their own, sell that one to the effected teams fans. Just imagine if Coventry were denied a place in the Premier League just so Rangers and Celtic could be slotted in!!
Thirdly could you imagine the response from Scottish fans and the SFA if the SPL were the same cash cow as the Premier League is and Arsenal and Spurs wanted to join? They would soon get told to f**k off, as we all know.
If I am utterly honest I do not care about Scottish Football, the SFA has had plenty of time to sort things out and make the SPL a more competitive league, they have consistantly failed to do so, I think before he became Coventry Manager Steven Pressley proposed some quite significant changes that were promptly ignored due the old guard at the SFA not wanting to give up any control.
