Milan are ready to strenghten their defense after the too many poor performances during this season.
According to Tuttomercatoweb.com Rossoneri are keeping tabs on Olympique de Marseille centre-back Nicolas N'Koulou in order to replace three important departures.
In fact Alex, Philipe Mexes and Cristian Zapata are all expected to leave Serie A this summer.
