Diego Costa is one of those players that you hate when he is against you, but just adore when he plays for your side.
The Brazilian-born Spain international has been back to his very best this season after suffering a huge dip in form during the final miserable months of Jose Mourinho's reign as manager.
However, in this third season at Stamford Bridge, the former Atletico Madrid man is now back to his very best and he has 17 goals in 25 league games to his name.
Of course, Costa is well-known for being a hot-head on the pitch and a walking timebomb when it comes to having disciplinary issues.
On the training ground, it's a different story. Costa's personality and rogue nature is very endearing to his Chelsea teammates and he is known to be very popular around the training ground.
So it was very funny when Cesc Fabregas decided to crop his international teammate out of a picture he posted on Instagram - quite deliberately so, too.
Costa, not a man to take such a slight lying down, decided to respond to Fabregas' decision with a simple, but effective emoji.
It just goes to show that Costa isn't all blood and thunder and he does have a personality behind his ultra-aggressive style, and indeed, the camaraderie the Blues are displaying was all but gone towards the end of Mourinho's tenure.
Current boss, Antonio Conte, has made the club more like a family again it would appear and now that they sit 10 points clear at the top of the Premier League, the good times are firmly back.
Next up is an FA Cup quarter-final tie with Mourinho's Manchester United. A goal for Costa would certainly feel like his emoji to Fabregas for his old boss.
