Since joining Chelsea in the summer Diego Costa has been highly impressive, scoring four goals in his first three Premier League games.
Despite impressing, the Spain international has had to face questions over his alleged age of 25-years-old. His form on the field suggests he could be younger, but his weathered face suggests otherwise.
Now the emergence of a new picture has strengthened the argument that Costa is in fact older than he claims. The photo above, which made the rounds on Twitter this week, shows a 17-year-old Costa looking not a day younger than his current self.
This suggests one of two things. The first is that Costa is an immortal being that never ages. The second is that he has always looked much, much older than he is. GiveMeSport is currently siding 60/40 towards the second.
It is not just fans and pundits alike that have raised concerns over Costa's age. Even his Chelsea team-mates have questioned whether or not he is lying about his age. Eden Hazard caused a stir recently by suggesting Costa must be lying about his age.
Speaking to Soccer AM, the Belgium winger said: "He looks old, I think he’s old. He is 25 but I don’t know if it is true."
It's an all too familiar controversy for Jose Mourinho, who hit headlines earlier this year after accusing Samuel Eto'o of lying about his age. The Special One was filmed speaking in private when he joked about the Cameroonian's age.
Mourinho said in February: "The problem with Chelsea is we lack a scorer. I have one [Eto'o] but he's 32. Maybe 35, who knows?"
Eto'o later branded Mourinho a "fool" for making the comments and also mocked him with his now infamous 'old man' goal celebration.
But Costa does not need his wrinkled features to cause a stir on the Premier League. His playing style has already irked rival Premier League managers with Everton's Roberto Martinez feeling obliged to publicly criticise the striker.
"There are certain foreign players who come to the Premier League who need to understand the ethics and the culture," Martinez said after the game.
"The behaviour in the British game is unique. The last thing you want to see is disrespect from a player to another player and I am sure he will learn that very quickly."
