I cant see them separating out again tbh. all that work and pissing people off for it to last a season?
The answer lies in 2 questions -
What has the merger done for those communities?
and
What has it done for football?
To my mind there has only been 2 necessary and successful mergers in the past 10 years and one of those may need to split due to demographics in the next 5 years.
