Jekyll and Hyde, Laurel and Hardy, Chelsea home form and Chelsea away form - they couldn't be more different if they tried. And so despite the amazing emotional high of yet another massive European night and comeback at Stamford Bridge on Tuesday, it's hard to be entirely confident as Chelsea head to Wales for the undercard* of Sunday's two Premier League matchups.
It doesn't help that Chelsea have not had much joy, if any at all, at the Liberty Stadium. Oh, why oh why couldn't it be called Oligarchy Arena? We all remember the Eden Hazard ball-LAD episode from the last time we were there. Previous to that, we struggled to back-to-back 1-1 draws, one of which needed a 93rd-minute own goal from Swansea for Chelsea to even get a point. That may have been Jose Bosingwa's greatest Chelsea cross ever.
The Blues have actually never won away to Swansea in the top flight (or in either cup), our last positive result coming in 1983 back in the confines of the old Division 2. Three legends, Kerry Dixon, John Bumstead, and Pat Nevin scored one each in a 3-1 win. We might need similar impact from our current and budding legends in this one.
* You should be rooting for Liverpool to win and City to drop three points. This would leave Chelsea in control of their own destiny with respect to the Reds when we go visit them in a fortnight and also reduce Manchester City's advantage to just one point with assumed victories in their two games-in-hand.

Swansea City team news: No major injuries to speak of for the Swans, leaving interim manager Garry Monk with a full complement of players to choose from. This should mean starts for dangermen Wilfried Bony (striker), Michu (support striker), and Jonjo Shelvey (dark lord). Speedsters Wayne Routledge and Nathan Dyer will look to torment our fullbacks, while the center back pairing of Ashley Williams and Chico will hope to contain the Chelsea attack.
With Fulham and local rivals Cardiff both victorious on Saturday, Swansea are not yet completely clear of the relegation battle. Laudrup's sacking has lead to a return to more "Swansealona" ways, though Monk, a self-confessed Brendan Rodgers acolyte, only has two wins in twelve matches to show for it.
Chelsea team news: Eden Hazard is out with the injury he picked up against PSG, while many sources list John Terry as needing a late fitness test to be declared fit. No official sources seem concerned about the captain. Ramires is back from his suspension, while European cup-tied Nemanja Matic and Mohamed Salah are available for selection after the midweek rest.
It's yet another must-win, just as all remaining games will be must-wins as long as we win the previous must-win. The Chelsea mission is simple: keep winning.
Previously: This will only be the 27th all-time meeting between the two sides, with Chelsea holding an 11 to 6 edge in wins. Only two of the 11 wins have come away from Stamford Bridge however (in twelve tries), with Chelsea averaging less than a goal-per-game in Wales.
