"I thought we were low key. The crowd were frustrated, and it looked like it wasn't going to happen for us, but you won't see a better goal than Henry's this season," said Jackett.
"He was excellent, his delivery was very good, but we needed someone to attack those crosses, and we didn't have that.
"They had a bit more power than us in both boxes. I'm disappointed with the goal, but in terms of the football, we had the lion's share of the possession.
"No disrespect to Swindon, but this was a winnable game, and we didn't get out of low gear for most of the game."
