It is well known that the 'Azulgrana' are under resourced at left-back and it seems they have now decided on the man they want to compete with established star Jordi Alba.
Recently centre-back Thomas Vermaelen has had to play out of position when Alba has been rested, but he does not provide the attacking impetus Ernest Valverde requires.
Lyon's left sided fullback could be the man they are after to solve this problem, according to British publication 'MailOnline'.
The Le Havre youth product shares the athletic qualities and attacking mindset of his namesake, Benjamin, the Manchester City defender.
He joined Lyon in 2017 and after making 44 appearances, scoring 3 goals, he will command a large transfer fee if he is to make the move to the Catalan giants in January or the summer.
