The French defender was only signed 12 months ago but has been left without a clear pathway for his development
Chelsea defender Malang Sarr saw a late loan move to Greuther Furth collapse on deadline day, despite travelling to Germany to complete the move.
The Bundesliga side were negotiating the move and were preparing for a medical, but talks for the 22-year-old couldn't be concluded.
The free transfer signing from Nice had struggled to find a transfer due to his relatively high wages at Stamford Bridge. Having spoken to his agent, Federico Pastorello, earlier in the week, the central defender had fielded interest from Brest and Eintracht Frankfurt but no switch occurred.
