Can't agree with that to be honest. European football is European football. Winning it guarantees an automatic CL spot. It also sets you up for for playing the CL which is totally different to the PL. Some great away days / nights as well for fans. I agree is can put strain on the PL fixtures but so does the CL. I'd say bring it on!
Only teams with CL (or very near CL) capability...who for some reason failed to qualify or stay the course in the CL... already in board, quality squad numbers etc can do well in it.
Untd, Arsenal, Chelsea City...maybe Spurs...and similar teams in Europe.
The group stages are easy enough, but time and effort consuming. Then the big boy drop outs come in and the other group winners.
It would take an exceptional team to finish say 5th,
Then do well (semi minimum) in the Europa
And finish in the C L places
Then mount a viable CL campaign
So no, IMO, it doesn't set you up for the CL - at best its season 4...if you're lucky, in a 6 or 7 season progression.
And if I'm generous I see us at year 2 atm.
