Do they ever play away after Europe? Think they have once this season and that was against us! They're having an easy ride with the Europa in comparison to Spurs going to Arsenal after their match.
My take on post-away Europa games and PL fixtures is the following:
1) Performance expected to drop after a mid-week European game. More so if the distance involved is considerable. Less time to prepare for the next game is as much a factor as travelling.
2) The impact will be greater the closer to the weekend the game will have taken place - Thursday night Europa the prime incidence.
If one accepts these are givens: Then one should apply the following logic: If the team's results will suffer, and they usually do, with the better teams averaging (ballpark) 50% more points at home than away (let's say 45-30 in the season). So it follows that an away game is to be preferred if performance will dip. Far better to lose one point (lose instead of draw) that 2 (draw instead the most frequent home result which is a win). The argument about the strength of the opponent is also worth making but the stronger teams also most likely playing in Europe.
