For me, I'm only seriously interested if Everton are involved. Half interested, and will watch in the quarter finals and on, if there is an English team playing (like wanting to see the RS humiliated). Not interested in the slightest even if it's Barcelona vs Real Madrid.
The same applies When Charlie Stillitano has his pre-season competition. I attended when Everton came to town, will watch when other EPL teams play (or LA teams), but zero interest when it's Juve vs AC Milan.
I know I'm old school, and don't have the same interest as others, but I think the ESL will be successful internationally (maybe it belongs in the USA), but the EPL will be where my real interest and passion will remain.
So ESL? I would probably watch a few games before losing interest and go on a hike instead. Everton vs Stoke? I'd still get up at 4am to watch :-)
