Manchester City have struggled defensively this year after conceding 19 goals.
The club decided against replacing Vincent Kompany and they suffered a further blow with the injury to centre back Aymeric Laporte.
According to
L'Equipe, Barcelona defender Samuel Umtiti could be set to join Manchester City.
City 'now view Umtiti as a possible January transfer amid a defensive shortage' at the Etihad Stadium.
Umtiti has made only five appearances for Barcelona this season so far and has missed 10 games through injury.
