Ok, so now that I have a bit more time....
My thinking is that one will get a very different answer depending on whom u ask...
A nationalistic Milan fan, say, one actually born and raised in Milan...will probably say:
Ok, but
not at the expense of the
Serie A...which according to his perspective, should be the club´s
primary target every season...the UCL for him, is icing on the cake...
For most international supporters of Milan, such as myself, nothing would please me more, but if I really think long and hard, would I really want it to come at the expense of say, the twice yearly games vs Juve and Inter? (Under the assumption that both those clubs would not be our opponents until much later down the "European League" season....and then, probably in a semi-final "one-off"....)
Which brings to question the structure of said league...? Are we talking traditional league structure here...home and away, then points to determine the ultimate winner?
Or something similar to the structure the present UCL employs...where there are knockout stages or "playoffs"...to use the NFL model?
So long as the "suits" in UEFA dont mess with the structure (and the money flow) of the UCL, I see it as a suitable substitute...and Platini has done much to render impotent the G-14....however, that being said, if said clubs feel that their income stream is being threatened (ie by Cup teams being allowed entry, and the amount of clubs allowed entry from the league table, eg top 4 in Italy being reduced) then we will surely hear more about the establishment of an European League..though how this could be established without the blessing of UEFA, is something I fail to understand....as I dont see FIFA saying "Yes" and UEFA saying "No" and there not being some fallout of nuclear proportions.
Now, if you ask Berlusconi, he would, I am sure, say: "Sure! Milan are Italy´s best performing club in European competition...its in our DNA..." (But who knows...he is a politician after all, and so your guess is really as good as mine what he might say).
If I were Berlu, and all things being equal with regard to the establishment of said league (ie UEFA being impotent to stop, or sanction participating clubs or players) I would abandon Serie A and its plethora of problems, and be Italy´s representative in the: "European Premiere League"..or whatever moniker it is christened with.
