Two other players, Mathis Amougou and Ishé Samuels-Smith, will join Strasbourg permanently. Meanwhile, Sarr will join Kendry Paez and Mike Penders, who are already on loan from Chelsea.
Sarr, a talented French Under-20 player, will be happy to return to his old club and help them compete for a spot in the European competition in the French Ligue 1.
Chelsea has released a brief statement confirming the loan deal, which suits both parties. The statement says that Sarr will join Strasbourg for the season and that the club will monitor and support his development throughout the loan.
Sarr made his Chelsea debut in a match against ES Tunis and featured in every matchday squad as the team became Club World Cup champions last month. This is another opportunity for him to gain experience and develop his skills in the French first division.
