There are two sides to every story, even in football.
Such was Barcelona's elation at their history-making comeback in the Champions League that they suffered something of a European hangover in their La Liga game against Deportivo.
As for Paris Saint-Germain, a 2-1 win over Lorient has done little to amend their miserable week after their humiliating collapse at the Nou Camp.
Unai Emery and co will not be forgetting about that result for a long time.
PSG now need to move on, as they sit just three points behind Ligue 1 leaders Monaco and still have a pretty good chance of winning their fifth title in a row.
Their ridiculous Champions League exit threatens to cast a shadow on their season no matter what happens, and they face a fight to ensure that it isn't the moment that defines their campaign.
PSG are still furious
The trouble is, the Parisians don't seem to be doing a very good job of putting it behind them.
While they must be angry with themselves for allowing Barca to score three goals after the 88th minute, the visitors were also suitably livid with the referee.
A petition to have the game replayed has now reached over 200,000 signatures, though that's never really going to happen.
What is happening, report Marca, is that PSG have sent UEFA a video dossier detailing eight incidents which they felt the officials got wrong.
The eight incidents
- Javier Mascherano handled the ball, but it was deemed unintentional.
- Gerard Pique could have been sent off for pulling Edinson Cavani's shirt while already on a yellow. Cavani would have also been through on goal had he got past the defender.
- Neymar was looking for contact when he won a penalty.
- The Brazilian was also a little lucky to stay on the pitch after appearing to stamp on Marquinhos.
- Luis Suarez threw himself to the floor, but while the ref didn't give a penalty on that occasion, he didn't book the former Liverpool man for simulation either.
- The game wasn't stopped despite Pique handballing from a PSG cross.
- Mascherano hacked down Angel Di Maria, who was through one-on-one with the goalkeeper. No penalty.
- Barca's fifth goal came from a penalty, won in typically controversial circumstances by Suarez, who probably didn't need to go down.
PSG have compiled the dossier with the help of top international referees as well as press cuttings, so they've clearly gone to some lengths to prove their point to UEFA.
Unfortunately, what they'd like most is for another chance at the game, and that's just not going to happen.
Was the referee to blame for PSG's defeat? Have your say in the comments.
