Chelsea were given a chance to sign Paris Saint-Germain fullback Layvin Kurzawa.
According to Goal, the French international was offered to Blues boss Thomas Tuchel.
However, the German, who has worked with Kurzawa at PSG, is hesitant about the deal.
Chelsea are dealing with injury issues at left back, with Ben Chilwell out for most of the season.
They are still assessing options in the transfer market regarding a temporary left-back signing until the end of the campaign.
