Barca will allegedly demand a fee of £21 million for the centre-back, however.
David Moyes is keen to bolster his central defensive ranks at the London Stadium this summer.
Fabian Balbuena has already left whilst Angelo Ogbonna and Craig Dawson are ageing.
Meanwhile, the jury is still out on Issa Diop.

West Ham chasing Barcelona ace on loan with obligation
It seems as though Moyes wants to bolster his defensive ranks by signing Clement Lenglet.
Football journalist Ekrem Konur broke the news last week that the Hammers could look to sign the 13-capped France international.
And now Sport are claiming that West Ham want 26-year-old on loan with an obligation to buy. Barcelona will allegedly demand around £21 million for Lenglet.
We think that Lenglet would be a decent addition to David Moyes’s side this summer.

Top class performer
In 33 La Liga appearances for Barca last season, the 26-year-old averaged 1.1 tackles, one interception and two clearances per game. He also won an average of 1.8 aerial duals per match (Who Scored).
The Barcelona ace is very comfortable with the ball at his feet. Lenglet made 69.7 passes per game on average during those outings and recorded and incredible completion rate of 92.1% (Who Scored).
If West Ham can pick him up on loan with an obligation to buy for around £20 million it would be very good business for the club.

Whether the owners are actually prepared to make it happen, however, is another matter entirely.
