Olympique Marseille defender Nicolas N'Koulou is being tracked by West Ham United.

The Daily Mail says West Ham are monitoring N'Koulou as they prepare to lose Winston Reid.

While Sam Allardyce was ensuring his team were riding high in third position in the Premier League on Sunday, clubs scouts were dispatched to watch versatile Cameroon international N'Koulou.

The 24-year-old N'Koulou played in the middle of a three man defence as Marseille beat Metz 3-1 on Sunday.
