David Luiz is criticised for many things, but whatever knocks come his way, it seems his confidence knows no bounds.
Sold by Chelsea to Paris Saint-Germain for £50 million this summer, the Brazilian endured a torrid end to the World Cup with poor displays against Germany and Holland contributing heavily to Brazil's humiliation in their final two games.
Is David Luiz right that Chelsea will miss him next season?
Those performances came on the back of an unfulfilling season where he was replaced by Gary Cahill in Chelsea's defence, forced by Jose Mourinho to watch on from the sidelines.
He is adamant the Blues will be worse off without him playing at Stamford Bridge this season, though.
"I have to believe that Chelsea or any team will miss me," he was quoted by The Sun (subscription required).
Err, like a hole in the head, David.
The 27-year-old is a player who carries many talents in his repertoire, but as a defender, he has shown enough times in his career that he is as much a liability as he is a class act.
There's nothing in between where Luiz is concerned—he's either stunning one week or woeful the next. At Chelsea, the latter became much too frequent for Mourinho's liking.
Championship-winning teams can rarely carry players, least of all defenders and Mourinho's sale of Luiz came at the perfect time for the club and player.
"I’m not arrogant but I’m confident in my own abilities," he continued.
"Paris paid a lot for me so they obviously believe in me—it is nice to be at a club where they really want you and where they show belief in you."
In May, that was possibly true of PSG. Despite the price tag, the Ligue 1 champions had bagged one of the biggest names in European football.
Post-World Cup, however, and Luiz has a different reputation altogether. Brazil 2014 has made him damaged goods.
Laurent Blanc must surely be questioning the wisdom in paying such a high sum for his services. Especially as PSG have recently been reprimanded by UEFA after breaking Financial Fair Play regulations.
Chelsea, meanwhile, have wisely reinvested the cash from Luiz's sale. In offloading him, they have brought in Cesc Fabregas and Filipe Luis to strengthen in two key areas.
Their combined transfer fees still left £8 million in loose change that was put toward bringing Diego Costa to west London.
When the Spanish international is putting in the kind of display like he did against Real Sociedad this week, scoring the goals Chelsea craved last term, it's difficult to see how Mourinho will miss Luiz's unpredictable performances given the changes his departure has helped bring about.
The Blues look a different team altogether now. They look ready for success once more.
Wherever he travels, Luiz's character is such that he will always enjoy a special relationship with supporters of his club.
Chelsea fans adored how he embraced the English language, manipulating slang words to become a "geezer" like them.
In the modern era, he is unique in that sense.
As a player, though, he always left Chelsea supporters feeling underwhelmed. With so much talent, too often he allowed his emotions to get the better of him, making poor decisions that impacted games.
Now he's gone, that problem has gone with him.
In his place is Mourinho's Chelsea and that's bad news for the rest of the Premier League.
