Rangers and Celtic, especially in the PL are miles miles bigger than Arsenal and Chelsea mate. In truth they are probably bigger than United and Liverpool too. The support both would garner in England, Ireland and North America would be huge. Chelsea are not even close to being comparable.
Pretty much spot on this .
I think some folks are pandering to the narritive the Prem is nothing without Lfc & Manu .
In fact if and its a big if the 2 Glasgow clubs came in it would allow traditionally Big clubs likeSpurs, Villa , Leeds & Ourselves to flourish .
Possibly seeing a much fairer playing field for upto even 8 to 10 teams having a chance to be Champions.
The support from overseas esp America would be just as good and the fans in the UK I would be sure would fully be behind it with the full grounds we saw pre covid.
It really wouldnt be the end of football.
