Chelsea have stepped up talks over a possible deal for Borussia Monchengladbach forward Marcus Thuram.
The 25-year-old is out of contract in the summer and Chelsea are exploring a deal now after contacting his entourage earlier in the window.
Thuram has interest from a number of clubs but had been considering seeing out the season to leave as a free agent.
Chelsea have also shown an interest in Thuram's brother, Nice midfielder Khephren, 21, as an alternative option to Benfica's Enzo Fernandez.
Newcastle have also been monitoring Kephren while both clubs also like Kouadio Kone at Gladbach.
