Boss Glenn was seething after Marcus Bent and John McGreal took advantage of slack marking to head Ipswich Town home to a 2-1 Premiership victory.
The result was somewhat harsh after another fine display with the ball but despite dictating possession we only had Gus Poyet's goal to show for our efforts.
Add injuries to Les Ferdinand and Christian Ziege and, in Glenn's words, 'it wasn't a good day'.
"We punished ourselves with our marking from corners," blasted Glenn. "It was disgraceful really and if we don't get any better then we'll be punished again, simple as that.
"Managers can accept markers losing a player by half a yard, even a yard, but when three yards are given on both occasions and you lose the points on the back of that, it's very frustrating and annoying I can tell you.
"At half-time, I said we can't concede again like that and the players have to make sure that over my dead body does it go in the back of the net. Someone wasn't listening.
"We were in control of the game for long periods and at 1-1 I really felt we were going to go on and win it.
"There are no excuses. It was poor defending, end of story. Sometimes you get away with it and the headers go over the bar but I'm sure they won't score two easier goals all season.
"We have to learn a lesson from it. If we go from now until the end of the season without conceding a goal from a corner, we'll have learnt from it and it will be a positive. We have to make sure that happens."
Glenn Hoddle branded our defending as 'disgraceful' after two goals from corners cost us dear at Portman Road.
