Brilliant idea. I’ve said this with my mate in the past. I’d go further and merge quite a few leagues. It would really up the strength and the funding for the teams.
I would also merge in Luxembourg with Holland and Belgium.
I’d join Austria and Switzerland.
Ireland, Wales, Scotland and Iceland.
Denmark, Sweden and Norway.
Merge the former Soviet states
Merge the former Yugoslav states
Czech, Slovakia and Poland
Greece and Cyprus
Bulgaria, Hungary and Romania
some would be easier than others and some may not be able to because of politics but wher possible it should be being looked at.
Would make European competitions much stronger as well.
