Club Brugge chairman Pol Jonckheere announced the deal ahead of their Europa League clash on Thursday.
“The coach signed a one-year contract last summer with the option for another year. The club have now exercised that option so Adrie Koster is our coach for the next year,” Jonckheere said.
“I feel excellent here and I am happy that Club Brugge are satisfied with my work,” said Koster.
