Coach René Desaeyere left Ratchaburi FC just after two matches in charge, according to reports from Thailand.
The 70-year old was appointed as the replacement of Christian Ziege who left the club in February due to family affairs.
During his short stint with the Thai League 1 side, he suffered 2-1 and 2-0 losses against Bangkok United and Chiangrai United respectively.
His 19 days on duty has been the shortest period of time being in charge for a head coach in Thai League 1.
“We have to say thank you for René Desaeyere for his past three weeks. Now we have to find a new coach,” Ratchaburi FC wrote on their official website.
Ratchaburi appoint Thai coach Somchai Maiwilai as the caretaker for the league game against Nakhon Ratchasima this Sunday.
