Mbemba once stated in an interview that he believed his birthday was around 1990, which would make him 25. The centre back began his career in his homeland, where his date of birth was registered as August 8, 1988. By the time he came to sign for Anderlecht in 2012, his new birthday was stated as August 8, 1995.
However, during qualifying for the 2012 Africa Cup of Nations, Congo registered him as a November 30, 1991 birth. And to add to the confusion, Mbemba himself has been quoted as saying he was born in 1990.
Newcastle, however, are said to be relaxed about the situation surrounding a player they regard as the best defender in the Belgian Jupiler League. He will follow Anderlecht team-mate Aleksandar Mitrovic to Tyneside after the striker joined in a £12.5m deal earlier this week.
