There was frustration from the terraces as Pompey failed to break down AFC Wimbledon’s stubborn defence at Kingsmeadow.
That only grew when Terell Thomas headed home the winning goal for the hosts deep into stoppage-time.
Kenny Jackett fully understands why he is on the receiving end of some stick from the Fratton faithful.
And he knows it increases the pressure ahead of Lincoln’s visit to the south coast on Tuesday evening.
The Blues boss said: “The crowd are frustrated with the team and with me. I can hear that and I can feel that.
“It’s a privileged position to be manager of such a fantastic club and I’m experienced to know that Tuesday night is key.
"The crowd are frustrated with the team and with me. I can hear that and I can feel that."
“The position we’re in is very frustrating and I can’t say we’ve got it right because things haven’t flowed for us.
“We have to look at some of the good things we’re doing, but also find an edge and that’s our responsibility.
“So we have to keep persevering and working hard. I think the players have good character and the ability is definitely there.”
Pompey had 22 shots against the Dons – and 10 of them were on target – but ultimately had nothing to show for their efforts.
Jackett said: “It’s very disappointing because we enjoyed the lion’s share of the game and had the ball in some very dangerous areas.
“There were obviously some chances that their keeper was equal to and we couldn’t quite make it happen in the final third.
“It’s such an important part of the game that you are incisive in those areas and we weren’t, despite controlling long periods.
“We didn’t make it pay and were then undone by a sucker punch right at the end. It looked like we gave Thomas a free run at it.
“It’s the zero going forwards rather than the one against that’s really cost us because we didn’t have the cutting edge.
“We’ve been on top in the past two matches and got one point out of six – that’s frustrating, but the bottom line is points.”
