Tunisian Adel Sellimi succeeded his compatriot Nassif al Bayawi as coach of the QNB Stars League team Al Khor Club.
Bayawi has joined Al Kharaitiyat, replacing Yasser Sebaei.
The Knights started the season under Frenchman Laurent Banide before Bayawi took over the reins following a series of negative results.
Al Khor Sports Club President Hassan Juma al Mohannadi presided over the ceremony, in which Sellimi signed a one-season contract.
The team management thanked the services rendered by Bayawi and wished him success with Kharaitiyat.
Al Khor finished eighth in this season's QNB Stars League with 24 points.
Sellimi became the coach of Markhiya, who were relegated to the Second Division after finishing at bottom of the table, when The Oryxes parted ways with Qatari coach Yousef Adam following their 2-3 loss to Al Kharaitiyat in Week 16 of the QNB Stars League.
Sellimi has coached some Tunisian clubs and had technically been involved with his national team.
During his illustrious career as a striker, he played for top Tunisian side Club Africain, French club Nantes and German side Freiburg.
Youssef Msekni's operation successful
Al Duhail SC announced on Wednesday the success of the surgery the team's star and professional footballer Youssef Msekni underwent at a Pittsburgh hospital, US, after suffering a cruciate ligament injury.
Msekni is expected to start rehabilitation programme on Wednesday in the United States before returning to Doha to complete his recovery under the supervision of Dr. Faisal Moudab, the Al Duhail Club doctor, who followed the surgery process moment by moment.
He was injured in the last match in the Qatari league against Al Sailiya after coming as a substitute.
Msekni's injury was a shock for his fans whether in Doha or Tunisia, as the injury will prevent him from participating with his team in the upcoming World Cup Russia, which is scheduled to start in June.
Dr Moudab previously announced that the absence of Msekni will continue for a long period of six to seven months, as the player needed a long period of rehabilitation to ensure reaching ideal level of treatment.
