Chelsea are considering moves for Sevilla centre-back Jules Kounde and Juventus star Matthijs de Ligt as the Blues look to revamp their defensive options, according to reports.
Defensive duo Antonio Rudiger and Andreas Christensen are currently set to walk away for free at the end of this season when their contracts expire, though the west Londoners are still negotiating with the pair over new deals.
Chelsea held a strong interest in Sevilla star Kounde last year, though the Blues failed to meet the Spanish club's £67million asking price before September's transfer deadline.
