Paris Saint-Germain's David Luiz is renowned for many things amongst football fans.
Luiz has flown somewhat under the radar since Brazil's embarrassing 7-1 defeat to Germany in the 2014 World Cup semi-finals, but he's back with another piece of football magic.

On this occasion, though, there was no sign of the 29-year-old's cheeky smile as he scored a bizarre own goal against West Brom during a pre-season friendly on Wednesday.
Watch the blunder below.

We see these types of own goals on a regular basis: player crosses ball, defender diverts past his own goalkeeper.
But this is different. Saido Berahino certainly puts his cross into a dangerous area, but it literally trickles across the face of goal.
Luiz has time to make a decision, with the obvious one being to clear for a corner. This is David Luiz we're talking about here, though, so he slides and inadvertently knocks the ball under goalkeeper Kevin Trapp.
Fortunately for Ligue 1 champions PSG, the centre-back's 15th-minute slip up didn't prove costly as Adrien Rabiot and Lucas Moura were on hand to secure a 2-1 victory.
Imagine that, little ol' West Brom beating European powerhouses PSG.
It was not meant to be, with Rabiot's rasping 18-yard equaliser finding the roof of Boaz Myhill's net shortly after being introduced in the second half.
Moura soon added a second from a rebound to spare PSG's blushes.
The pre-season friendly in Austria was Unai Emery's first game in charge after succeeding Laurent Blanc as manager.
Upon his arrival at the Parc de Princes, the former Sevilla boss revealed he was honoured to take over at such a big club.
According to Sky Sports, he said: "It is with great pride that I agreed to become the Paris Saint-Germain coach.
"The club has become one of the biggest in Europe over the past few seasons and I am both happy and honoured to be able to help realise its great ambitions.
"I am eager to meet up with my new players as well as the people who work tirelessly every day to help the club grow.
"I know that an immense fervour exists around the Paris Saint-Germain and I will be giving my best to ensure its millions of fans have a great deal to cheer about."
PSG's chairman and CEO, Nasser Al-Khelaifi, also revealed his delight at securing Emery, who steered Sevilla to Europa League glory last term.
"I am very happy to welcome Unai Emery as the new coach of Paris Saint-Germain," he added.
"Unai will bring to the club all his experience, his passion and his strong management skills and human qualities."
