Eden Hazard has questions about Diego Costa's age

Spain's forward Diego Costa gives a press conference at the Spanish national football team's CT do Caju training site in Curitiba on June 10, 2014

Diego Costa is 25 years old, but many people think he looks much older than that. And his new Chelsea teammate Eden Hazard is one of them.

During an interview with Tubes from Sky Sports' Soccer AM, Hazard mentioned his plan to get to the bottom of this.

"Costa looks old so I will ask him if he really is 25, even though he doesn’t speak English yet!”

Convenient, isn't it? Going to a country where he doesn't speak the language and can more easily evade questions about his age was probably all part of Costa's plan. Born in Brazil, Costa began his career in Portugal, then moved to Spain, where he eventually gained citizenship and joined the national team for this summer's World Cup. Now he's in England. Always moving before anyone can ask too many questions.

But we here at DT have unearthed a photo of Costa as a 10-year-old that only raises more questions...

We may never get to the bottom of this mystery, but if Eden Hazard suddenly disappears Diego Costa should probably be the prime suspect.
