Chelsea defender Malang Sarr has completed his loan with Porto.
The stopper joined Porto last summer after signing for Chelsea as a free agent from Olympique Marseille.
Taking to social media, Sarr declared: "Proud to be able to say that I played for this great club, forever grateful for this opportunity.
"I want to thank the fans for the reception and for all the support throughout the season, also to the people of the club.
"I wish my teammates the best for the future."
