I just don't get how it is so hard to see the difference of how much worse Eurpoa League is. All the naysayers who tout 'it's no different to Wednesday/Saturday', whilst correct about the time elapsed between that and a Thursday/Sunday being the same, miss a lot more relevant points.....
Champions League is sometimes split Tuesday AND Wednesday so you can and do have an extra day, you never do with EL (unless a rare Monday Night Football fixture).
More to the point as well, there are regularly 2-3 matches on a Sunday as well due to TV so Champions League sides often get a Wednesday/Sunday.
From the above it is broken up a bit and increased in terms of rest days.
In EL there are two more games to go all the way.
In EL you're regularly going to much further flung places than France, Spain, Germany, Italy and Holland. You get some treks in the CL too but far fewer and generally better trips and/or capital/main city clubs with better facilities!
And not to be underestimated is the prestige and subsequent adrenaline that you get with the CL including most group games. Running on that helps far more than the auto-pilot, tin-pot attitude and feel of he EL for most until it gets to the much later stages.
HUGE DIFFERENCES!!!!!
