Funny thing is to everyomne who goes 'where would these other teams finish in the prem', the answer is simple, theyd have a massive amount more money incoming through tv deals increased gates and cost of match tickets etc, increased profiles from playing in maybe the higehst international profile of any league...
So the question then comes downn to the size of the club and investment, put Ajax and celtic and porto etc in the prem with the support they have, the very astute way they conduct business for Ajax and Porto and their youth and scouting policies and networks and within a year or two of mid table adjustment they would be up near the top of the table fighting it out with spurs, the rs, us, arsenal etc for champs league places.
Playing in the Prem, Celtic would become a massive massive team, their destroy a huge amount of the leagues irish support base - especially so in america where they would become the only team followed, the commercial revenue they'd start to bring in would be phenomenal over a few seasons and theyd be packing out Celtic Park every week with 60k
