It has been reported that West Ham are making checks on the 20-year-old central defender, with manager David Moyes looking for a new central defender.
French club Strasbourg value the 20-year-old at £20 million, according to the report in the British tabloid.
According to WhoScored, Simakan has played four times in Ligue 1 for Strasbourg so far this season.
During the 2019-19 campaign, the Frenchman made 17 starts and two substitute appearances in the league, according to WhoScored.
Good signing for West Ham United?
Simakan is a promising and talented young central defender who is progressing well at Strasbourg.
The 20-year-old is one for the future, and it could take him a while to settle into life at West Ham, especially as he would have no pre-season with the London club.
What the Hammers need now is a defender who can make an immediate impact and who is established and has a lot of experience.
West Ham narrowly avoided relegation from the Premier League at the end of last season and could be involved in the battle for survival again this campaign.
