PHOTO: What exactly is Luiz doing in this celebration? Is this NSFW?

This could turn in to quite an explicit caption contest but do your best with this Chelsea photo, taken during their Champions League match earlier.

Sometimes photographs are better left without a caption, from sports writers that is, but there is no doubt this image may attract one or two comments from our readers as David Luiz is seemingly overcome with emotion after witnessing Chelsea bring their aggregate score against Paris Saint Germain to 3-3 at Stamford Bridge earlier this evening, Tuesday.

That scoreline is how the match concluded as the Blues booked their place in the final four of the Champions League due to the away goal ruling.

Jose Mourinho had to engineer a 2-0 victory if he was to secure continued European football for his side this season but will have perhaps suffered a heartache moment when Eden Hazard had to be substituted early (within 18 minutes) due to injury.

His replacement, Andre Schurrle, though had a chance to dazzle in his most natural position - and he certainly did just that - as the German attacker finished well in the first half before smacking the frame of the goal in the second half.

Playmaker Oscar, too, hit the woodwork and it looked as though it could be one of those nights for Chelsea, where they do everything but score the vital goal… until Demba Ba of all players struck the winning goal and Luiz had a celebration of his own in mind…
