You get the feeling that the jovial Eden Hazard is one of the biggest jokers in the Chelsea dressing room - so it was no surprise to see the Belgium international take the micky out of his teammate Thibaut Courtois following his mistake against Hull City on Sunday.
Courtois, who also represents Belgium at international level, conceded a soft goal at the KC Stadium following an uncharacteristic poor touch - but was let off the hook thanks to Loic Remy's late winning goal.
After the match, Hazard took to Instagram to take a cheeky dig at his compatriot, posting a photo of the pair of them smiling alongside the caption: "Do you want to dribble like me?? Hahahaha thank you for the saves".
Courtois made amends with superb triple-save
Courtois made amends for that surprise error by producing a superb triple-save later in the match, as Premier League title favourites Chelsea maintained their six-point lead at the top of the table.
Chelsea boss Jose Mourinho might have considered dropping Courtois for the Blues' next match after that blooper - he did just that for last month's win over Everton following a couple of unconvincing displays against Aston Villa and Manchester City - but the world-class goalkeeper has the chance to prove that he's still fully focused during the international break.
Courtois to face Cyprus and Israel
Courtois will start ahead of Liverpool's Simon Mignolet for Belgium's forthcoming Euro 2016 qualifiers against Cyprus and Israel before Chelsea's next Premier League match against Stoke City on April 4.
Courtois, though, wasn't the only world-class 'keeper who endured a difficult Sunday.
De Gea and Neuer also made mistakes on Sunday
Along with Manchester United's David de Gea and Bayern Munich's Manuel Neuer, Courtois is widely regarded as one of the world's top three goalkeepers - but both De Gea and Neuer also made uncharacteristic mistakes in their respective matches.
De Gea allowed Daniel Strurridge's fierce shot to beat him at the near post in the Red Devils' 2-1 win over Liverpool, while Neuer inexplicably allowed a tame shot from Borussia Mönchengladbach's Raffael to cross the line.
Courtois is the world's best goalkeeper
Despite Courtois' latest mistake - and the fact he has looked a little nervy at times this season - there's no doubting his immense class and potential.
No goalkeeper was better than Courtois over the course of 2014, despite the fact Neuer was nominated for the 2014 Ballon d'Or award, following his magnificent exploits with loan club Atletico Madrid.
Courtois also performed well at the World Cup finals in Brazil and continued impressing during the first half of the 2014-15 campaign with Chelsea.
Many would argue that Courtois is already the best in the business - and it's hard to disagree with that point of view.
