Soungoutou Magassa was born on 8 October 2003 in Stains, France, and developed in the Monaco academy. He came through as a midfielder who could also play in defence, a useful profile in a club known for producing physically strong, tactically flexible young players.
At Monaco he broke into senior football as a holding midfielder and occasional centre-back. His middle development was shaped by Ligue 1 minutes, European squad exposure and the need to play with discipline in a team full of attacking talent. His ability to protect the defence and pass simply made him increasingly attractive outside France.
West Ham United signed him as a young defensive midfielder with room to become a Premier League-level ball-winner. In east London he offers height, reach and positional coverage in midfield, while also providing emergency defensive flexibility. His adaptation depends on handling the league's tempo and improving his distribution under pressure.
For France he has represented youth national teams and has also been eligible through family background for other international consideration. The senior France midfield is extremely competitive, so he remains a developing candidate rather than an established full international.
Standing around 1.88 m, Magassa is a right-footed defensive midfielder with long legs, tackling range and the ability to drop into the back line. His profile invites comparison with Aurélien Tchouaméni in broad Monaco terms, though Magassa is still earlier in the curve and more purely defensive at this stage.
