RB Leipzig has signed defender Mohamed Simakan from Strasbourg on a five-year contract, the Bundesliga club said on Monday.
Leipzig did not disclose the financial terms of the deal but said the 20-year-old centre back would join on July 1.
Simikan, who was linked with a move to AC Milan last year and is a France under-20 international, has played 19 Ligue 1 games for Strasbourg this season but has not featured since having surgery on his right knee in January.
"Mohamed Simakan is a robust defender... who... can play both centre-half and full-back," Leipzig sporting director Markus Kroesche said in a statement.
"At the age of 20, he is still... capable of development, but has already played two seasons in Strasbourg as a regular ... We are happy that he has chosen us despite numerous other interested parties."
