Chelsea are in talks over a free transfer move for France Under-21 international Malang Sarr, who left Nice in the summer and is weighing up offers from a host of clubs.
The deal would be with a view to sending Sarr out on loan but it is understood that no decision has been made with a host of Bundesliga and Serie A clubs, including Bayer Leverkusen and Schalke, offering good terms.
Discussions with Sarr's representatives mean that Chelsea are now lining up what could be their sixth signing of the summer, having already completed deals for Hakim Ziyech and Timo Werner for a combined cost of £91 million ($114m).
