PSG's clash with Chelsea on Wednesday will see David Luiz return to Stamford Bridge for the second time, having infuriated supporters of his former club during last year's victory.
If clashing numerous times with Diego Costa had not been enough to deeply upset the crowd, Luiz certainly touched a nerve when he celebrated his late equaliser. He was booed throughout the game and subsequently admitted that he had lost control of his emotions.
However, Wednesday night gives both parties an opportunity to wipe the slate clean. Given the passion which Luiz showed in three-and-a-half-years at Chelsea, the least the club's fans owe him is their forgiveness.

Taking one for the team in Munich
The highlight of Luiz's time at Chelsea was his colossal display in their shock Champions League final victory over Bayern Munich.
Despite having struggled with a hamstring injury in the build-up to the game, Luiz played through the pain. He claimed last year that he had a permanent indentation in his right leg as a result.

Playing on the edge
Chelsea have struggled for form this season and their current players have come under fire from the supporters for an apparent lack of drive.
Few would have said the same about Luiz during his time at the club.
Whether he was falling to his knees after Didier Drogba's winning penalty in Munich, or crying after losing FIFA Club World Cup final 1-0 to Corinthians in 2012, emotion always poured from the Brazilian when he wore Chelsea's shirt.
He infuriated opposition supporters with his confrontational approach and was lambasted for smiling as he lay on the Old Trafford pitch, apparently trying to get Rafael da Silva sent off (and successfully so).
Having benefitted on so many occasions from Luiz's win-at-all-costs attitude, Chelsea fans have no right to resent him for it now.
They were wrong to boo him at Stamford Bridge last year, and there should not be a repeat.
In a sport where supporters are quick to forget those who have brought them success, Chelsea fans have been exceptional in their treatment of Frank Lampard, Petr Cech, and Juan Mata.
Having built a reputation for treating former players with dignity, they must not throw it away.
