Chelsea had planned to recall Mamadou Sarr from Strasbourg in the winter transfer window, terminate Aarón Anselmino's loan deal at Borussia Dortmund, and send Gabriel to Strasbourg as a replacement for Mamadou Sarr.
However, this transfer chain has now hit a major snag.
Where lies the problem? Aarón Anselmino is unwilling to move to Strasbourg on loan.
Without a high-caliber replacement for Sal to join Strasbourg, the recall deal for the defender cannot be completed.
