Crystal Palace will play two extra matches in February to stay in the UEFA Conference League after a 2-2 draw with KuPS from Finland.
This draw means Palace missed a direct spot in the last-16 and now must play a two-leg play-off on 19 and 26 February.
Palace now face Leeds United in the Premier League on Saturday and Arsenal in the Carabao Cup on Tuesday.
Glasner says the draw was disappointing and joked that Leeds might already know who will start, since only 11 players were rested.
