Xavier Tshimanga Kamaluba Ntite Mukendi Mpoyi Mbuyamba (born 31 December 2001) is a Dutch professional footballer who plays as a centre-back for Eerste Divisie club Volendam.

[2][4] He ultimately made 11 league appearances for Maastricht throughout the season and his performances reportedly attracted attention from a host of European clubs, including the likes of Bayern Munich, Chelsea, Liverpool and Real Madrid.

[5] The move came about following an approach from Barça's academy director and former Netherlands international Patrick Kluivert, and saw him become the fourth Dutch player to join the Catalan side ahead of the 2019–20 season following the club's earlier acquisitions of Frenkie de Jong, Ludovit Reis and Mike van Beijnen.

[11] After a period of eight months of rehabilitation, he made his debut for the club's development side on 11 April 2021 as a late substitute and marked his return to action with a goal as Chelsea recorded a 3–1 win over Southampton U23.

[12] Due to his height, physical stature, aerial presence and proficiency on the ball, the latter of which has been accredited to his development at La Masia, he has often been compared to countryman Virgil van Dijk during the early stages of his career.
