Glasner says they were well worth the point, with Ebere Eze also having a goal questionably disallowed on the day.
"I'm very pleased with the performance today for most of the time,” he said afterwards.
“I think just at the end, we lost the ball too quickly and gave them two or three chances, but the defensive work was excellent, the players did a great job.
“We scored, but it was disallowed. We created two, three, four chances, but we didn't score, so that's why we take this point. It was a very good performance and a very good start to the season.
“I'm always talking about progress… last year we had a disallowed free kick at Brentford and we lost this year, we had a disallowed free kick and we drew! So the first step is the right one.”
We know the rule
On the disallowed free-kick, Glasner reasoned: “Honestly, I haven't seen the free kick, but we know the rule that you have to be one yard away from the wall.
“I think at the beginning we were. Maybe we made the step too early because you have to wait until the kicker kicks the ball… so, if this was the case, then maybe it's right.
“I think it's tricky because many teams are acting like this, but for us it's now finding solutions, adjusting. It was a great free-kick, a great goal, but unfortunately it didn't count.
“I was a little bit surprised, because VAR is handled very, very cautiously here in England, which I really appreciate. It's always about supporting the referee's on-field decision.
“But again, it's gone, so my thoughts are on Thursday, and my great team, who are always watching all the set-plays, will watch it again and find a solution so that in the next case it won't happen again that the goal is disallowed, and then we can celebrate and hopefully win.”
