We failed to take a couple of good chances at 1-0 up that would have put the game beyond Bolton's reach and then conceded a poor goal when we failed to clear our lines.
Dean Holdsworth cashed in on that mistake and instead of us being in charge, suddenly Bolton gained an extra yard and finished the stronger.
Glenn claimed: "It's happened too many times this season when we've been 1-0 up - West Ham last week, Middlesbrough away recently and now today - and we've had the key moments to win the three points.
"Simon Davies really should have scored a minute before half-time, that would have killed the game and then we played some beautiful football to open them up for Sergei not to take his chance. To be fair it bobbled up on him a little.
"Of course, 60 seconds later they equalise after what was such a poor bit of defending. We defended well all through the game and I couldn't see that goal coming. They were the key moments.
"Ben held his hand up afterwards but it was so disappointing to see that lovely football we played to open them up and not go 2-0 up.
"In many ways that is the story of our season. We create a lot of chances like that and then give sloppy goals away and we've got to improve on that next season if we want to achieve anything."
Glenn Hoddle was left frustrated as the key moments went against us in our draw at Bolton on Saturday.
