English Premier League club Newcastle has agreed a deal with Belgian club Anderlecht to buy Democratic Republic of Congo international Chancel Mbemba.
But just how old is Mbemba?
The defender's birth date recorded by Anderlecht is August 8, 1994.
However, according to documents obtained by CNN in 2013, Mbemba was registered by his two first Congolese clubs -- E.S. La Grace and Mputu -- as being born in 1988.
Yet for a Cup of Nations qualifier in June 2011, Mbemba's year of birth was listed as November 30, 1991. Here Mbemba is pictured in action against Ivory Coast's Yaya Toure.
Mbemba himself, thinks he was born in 1990.
Mbemba made 28 appearances for Anderlecht last season, who finished third in the league.
Newcastle has also signed striker Aleksandar Mitrovic (left) from Anderlecht.
For Newcastle fans last season proved a bruising experience, with the club narrowly avoiding relegation from the Premier League.
Newcastle started the 2014/20215 with Alan Pardew in charge of the first team, but midway through the season he decamped to Crystal Palace.
