The fabrication of players' ages continues to be a problem for football. One international -- Democratic Republic of Congo defender Chancel Mbemba Mangulu -- has "four different birthdays". Lefty Shivambu/Gallo Images/Getty Images/file

Mbemba was born in the Congolese capital of Kinshasa, as was another of the city's most famous sons French midfielder Claude Makelele, who played for Nantes, Marseille, Real Madrid, Chelsea and Paris Saint Germain.

Mbemba was registered by his first Congolese club - E.S. La Grace -- as having been born on August 8, 1988, according to one of the documents obtained by CNN. The documents -- showing Mbemba's various ages -- were provided by the Brazilian agent Paulo Teixeira, who was called in by E.S. La Grace to obtain money they claimed was owed to them by Anderlecht for training the player in his formative years. In attempting verification of these documents -- from FIFA, the various federations and clubs involved -- only the world governing body and the Belgian Football Assocation responded directly to CNN's request by saying they appeared to be authentic.

When Mbemba obtained a Belgian citizenship document in July 2011, a month after he arrived in Europe, his date of birth is now dated August 8, 1994. Paulo Teixeira
That meant when Mbemba played for Anderlectht's Under-19 team against Club Brugge in September 2011, the Congolese defender was now six years younger than when he had been playing for his first two Congolese clubs. A professional Belgian referee confirmed to CNN that the Anderlecht team sheet was the type of document used in Belgian football.

In April 2012, Anderlecht confirmed in a letter to FIFA that Mbemba had been sent back to Kinshasa, but later that year he returned to the Brussels club. The Belgian FA confirmed that this document is geniune. Paulo Teixeira
In April 2012, Mbemba was sent back to the Congo, but by August 2012 he was back at Anderlecht when he was given a three-year professional contract.
