Opposition view: Jackett laments 'poor goals' after Pompey are blown away by Cobblers
Pompey on a run of one win in six after heavy defeat
Portsmouth manager Kenny Jackett accepts he's a man under pressure after his side were soundly beaten 4-1 by the Cobblers on Saturday.
Pompey arrived at the PTS hoping to get their promotion challenge back on track following one win in five, but instead it was only derailed further by the rampant hosts.
Ryan Watson scored twice in two minutes, Fraser Horsfall headed in a third and then Sam Hoskins' audacious effort meant it was game over before half-time.
Ellis Harrison did manage a late consolation from the penalty spot but that did little to ease the anger of Pompey supporters.
"The goals are very disappointing," admitted Jackett. "We talked through them with the players afterwards - the first three were all set-pieces. We shot ourselves in the foot and it's frustrating because we're normally good at that.
'Two of them were free headers two or three yards out so they were both disappointing. There's a question mark with the free-kick for the first goal but it was a good strike.
"The fourth goal is a ball over the top. We were in control of the situation but it turned into an opportunity for them to chip it over the goalkeeper which they did.
"That effectively put us out the game which was very frustrating because we alway want to have a solid base to play off but the goals we conceded were poor and gave us a mountain to climb. We were basically only playing for pride in the second-half.
"We're obviously very disappointed and we need to be better because you want to compete in games. We had a couple of chances in the first-half and we could have had a penalty because I think John Marquis' header hit a hand.
"Every manager is under pressure and when you're 4-0 down at half-time that comes with the territory. The players are a good group and want to do well and we're confident we can turn it around."
