Sergio Akieme arrived at Barça B at age 21, from Rayo Vallecano. Of Equatorial Guinean descent, he began his football journey in the youth teams at Parla but joined Rayo at U18. In June 2017 he made his debut with the Madrid team, in the Second Division A against Sevilla Atlético. In the 2018/19 season, he played two matches in the top flight, and in 2019/20 played as a starter in the opening day match against Mirandés.
Akieme signs for two seasons, with two more optional, and has a buyout clause of 40 million euros. He's a very intense defender who likes to get into the area as much as possible.
