Liverpool's latest European meeting with Atletico Madrid continues to prompt debate over whether it accelerated the spread of coronavirus through the region.
But it isn't the first time the teams have clashed in circumstances that would be considered not quite the norm.
Ten years ago today, the Reds were at the old Vicente Calderon for the first leg of their Europa League semi-final.
Nothing too odd about that.
What was, though, was the manner in which Liverpool - along with the media and Reds supporters attending the match - had made the trip to the Spanish capital.
And all thanks to an unpronounceable Icelandic volcano that had previously lay dormant for almost 200 years.
The ongoing eruptions from Eyjafjallajökull meant that Liverpool's normal travel arrangements - which, as they are today, involve flying out to an away European game the day before the match - had to be changed.
With air space temporarily shut, Rafa Benitez's Reds needed to find other means.
That meant, the day after a 4-0 Premier League win at Burnley on the Sunday, the Liverpool's squad decamped to Runcorn train station to begin an epic(ish) journey.
This still being in the era when the media regularly travelled with the team to European away fixtures, the ECHO was able to observe the faint ridiculousness of what was to follow.
Indeed, Runcorn probably hadn't seen quite the level of excitement as 50-odd supporters cheered the players on to their early afternoon train to Euston.
The fun, though, really began once the train had arrived in the capital, with the next leg of the journey starting at King's Cross St Pancras.
It took the media 10 minutes to walk from Euston to St Pancras but the team bus, having been greeted by another 100 or so fans and more camera crews, took more than 16 minutes to get there.
And once inside, chaos ensued when those not part of the Liverpool squad were refused entry into a lounge they had previously been told would be available, leading to a stand-up row between the door attendant and a member of the media.
At least the Eurostar journey under the Channel passed without any real incident, with the Reds relatively untroubled as they strolled through Gare du Nord towards another bus.
Commanding the limelight, though, was James Bond himself, Sir Roger Moore, who was also on the train. And no, he too was neither shaken nor stirred by being in the presence of Benitez and his players.
It's worth remembering this was at a time when the relationship of the Liverpool boss with controversial owners Tom Hicks and George Gillett was strained to breaking point and even fans were becoming tired of his propensity to pick arguments with just about everyone.
Nevertheless, Benitez was in jovial enough mood to debate favourite yogurt flavours with the media while passing through the carriages.
Paris was the next stop on a damp Monday evening, the match still 48 hours away and the team having not even reached the halfway mark in their travels.
A 6am start, though, was required for everyone to be bussed to Gard Montparnasse and hop aboard a train bound for Bordeaux and, hopefully, the airport.
The SNCF train was then afforded the bizarre sight of Benitez holding his pre-match conference to the assembled media in the buffet carriage.
Quite what the other passengers, which included businessmen enjoying an early-morning beer, made of it all hasn't been recorded for posterity.
Yet put into context, it didn't seem out of place.
The nearer Bordeaux came, though, the more the reality began to dawn.
Would another train journey be required to complete the final 425 miles? Or had the volcanic ash cleared sufficiently for air space to have reopened?
It turned out to be the latter, the airport having not long opened on the squad's arrival. In fact, we were the only passengers there on the sole flight given permission to leave.
After what had gone before, there was a slight sense of anti-climax at matters returning to normal.
A trifling 23 hours and 30 minutes after leaving Runcorn station, Liverpool arrived in Madrid. Factoring in shuttle buses, the journey had required one plane, three trains and six automobiles.
The game? Oh, Liverpool lost 1-0 to a Diego Forlan goal, whose extra-time strike in the return leg the following week saw Atletico through on away goals.
But it was the journey and not the destination that anyone involved on that trip best remembers from a decade ago.
