"The Liverpool goalkeeper \[Freddie Woodman\] had the day of his life so congratulations to him. We kept believing until the end. It was really positive and this is what we take into the final weeks.
"I told them that I think it was our best performance here against Liverpool. We were very competitive here today.
"I showed them the stats. We were 2-0 down at half-time, and you could say 'we rest our power for the Conference League semi-final' then maybe lose 4-0, or something but we didn't.
"This performance will give us a lot of confidence for the rest of the season."
Palace's goal came in strange circumstances when Liverpool 'keeper Woodman was down with a knock, only for the referee to allow play to go on.
Daniel Muñoz took full advantage by lobbing the ball into the empty net.
But despite protests from the home side, and their supporters, Glasner believes the decision to award the goal was a fair one.
"It was a difficult situation because he \[Woodman\] made a big save but the ball goes to Muñoz," he added. "Everything goes so quickly.
"He could continue the game until the end and that's why we think it was the right decision. I think that this was okay."
