Palace beat rivals Brighton earlier this in February but they have failed to win a home game since November.
Speaking before Sunday’s game against Wolves, Glasner said: “I’m always realistic, and we’re not in the best moment right now. I understand, and I take responsibility for everything because I’m responsible for the whole team.
“Right now, I’m just not good enough to replace the players we sold. I’m just not good enough to integrate the new players in a way to play the same way like we did, and I’m not good enough that we can cope with the schedule we had.
“On the other side, I was good enough to play the best season ever [and] win two trophies.
“We are playing a better Premier League season than [in] eight of the last 10 seasons. We play European football, and that is the reality.”
Glasner is the most successful manager in the club’s history having won the FA Cup last season and the Community Shield.
Palace host bottom of the table Wolves on Sunday before the second leg of their Conference League tie with Zrinjski Mostar on Thursday.
