Chelsea are preparing to open talks with Andreas Christensen at the start of 2018 after the young Dane impressed when replacing David Luiz in the starting XI, reports claim. The 21-year-old’s current £35,000-a-week deal expires in 2020 but club chiefs are keen to tie him down on a more long-term basis. Christensen has stepped up since Luiz’s public falling out with Chelsea boss Antonio Conte and he has started 16 games in all competitions in this season.
