Chelsea are reportedly considering bringing Thorgan Hazard back to Stamford Bridge.
The 24-year-old - brother of Blues players Eden and Kylian - is currently plying his trade in Germany, having joined Borussia Monchengladbach from Chelsea in 2015 on a four-year deal.
According to Bild, Antonio Conte's side still retain an interest in the Belgian and could be tempted to reunite the attacking midfielder with his siblings.
Thorgan, who has previously indicated that he could be open to a return to English football, has scored five times in 13 league games for Die Borussen so far this season.
Eden has established himself as a key member of the team since his arrival in 2012, while youngest brother Kylian arrived at the Blues' development squad this summer from Hungarian side Ujpest.
