Mateta's football career began on rough pitches in Sevran, where he learned to fight for every ball and never give up. He moved through small clubs like Olympique de Sevran and Drancy before being given a chance by Lyon in 2016. However, it was a loan to Le Havre in 2017 that helped him establish himself as a top striker, scoring 19 goals in Ligue 2.

Despite his success, Mateta was overlooked by France's top clubs, but he eventually caught the attention of Mainz 05 in the Bundesliga. The move was a risk, but it paid off as he refined his skills and developed discipline, movement, and timing. He soon caught the eye of Crystal Palace, who signed him in January 2021.

Mateta's first year at Palace was inconsistent, but he worked hard to improve and waited for his chance. Under manager Patrick Vieira, he finally broke through, scoring 16 league goals and helping the team qualify for European competition for the first time in their history. He also lifted the FA Cup and Community Shield trophies.

Mateta's performances earned him a call-up to the French national team, where he made his debut against Iceland and scored a goal. His "BOOM!" celebration has become iconic, and he continues to thrill fans with his powerful runs and finishes.

Coaches and teammates describe Mateta as "unshakable" and "obsessed," and his mentality is a key factor in his success. He is a target man with a powerful frame, but it's his determination and work ethic that set him apart.

Mateta's "BOOM!" celebration is more than just a gesture – it's a connection with the fans. He wants to give them joy and excitement, and when he scores, the stadium erupts. He is a true leader on the pitch, and his story is an inspiration to anyone who knows him.
