Andreas Christensen has been a revelation for Chelsea this season and has even ousted David Luiz from his position in the Chelsea back three.
The 21-year-old is currently on a £35,000-a-week deal which expires in 2020. But having entered the first team, club chiefs are keen to tie him down on a more long-term deal.
Christensen spent two seasons on loan with Bundesliga outfit Borussia Monchengladbach, before returning back to Stamford Bridge and has earned the trust of his manager with some consistent performances.
Chelsea will try to tie him down to a longer deal before the end of the season, and kill any hope of prying eyes on the Chelsea academy product.
