Glasner has been a key figure at Palace since joining the team, leading them to victory in the FA Cup final against Manchester City last season with a 1-0 win.
In addition to the FA Cup win, Palace also secured a win against Liverpool in the Community Shield, with Marc Guehi playing a crucial role in the team's success.
The transfer of Guehi to Liverpool was nearly completed but ultimately fell through when Palace failed to secure a suitable replacement.
Glasner was reportedly the driving force behind cancelling the deal, despite the club having agreed to a £35 million transfer fee with Liverpool.
In a recent interview, Glasner discussed his vision for the club, stating that he continually seeks ways to improve and that he would leave the club if he felt he couldn't make a positive impact.
