Ghana's Kamaldeen Sulemana made his first appearance in Southampton's 3-0 defeat to Brentford in the English Premier League on Saturday afternoon.
The Bees scored their first goal of the encounter through former Burnley defender Ben Mee in the 41st minute after a nice pass from Mbeumo.
The host scored the second goal this time Bryan Mbeumo turned goalscorer in the 44th minute. The third goal came through Mathias Jensen.
The 20-year-old's footballing career has led him to play for Rennes, the Danish club FC Nordsjaelland, and Ghana's Right to Dream Academy.
The attacker made his Ligue 1 debut last season with five goals in 27 games, but this season, due to injuries, he only managed one goal in 18 games before departing Rennes.
