Chelsea will be looking to strengthen at centre-back in the summer.
With Andreas Christensen, Cesar Azpilicueta and Antonio Rudiger's contracts all running out at the end of the season, the Blues could lose three of their prominent defensive figures for free by the time the summer window arrives.
The Blues have never been overly worried about spending money, and that doesn't appear to be an issue for the next window either. However, the problem is finding the right talent to replace players of that calibre.
