It was a result that was based on an impenetrable defensive display.
And Michael Jacobs was always confident that one goal would be enough for Pompey to win at Fleetwood.
That proved to be the case, as John Marquis headed home a Ryan Williams delivery to ensure the points would be heading back to the south coast.
The hosts never really looked like getting an equaliser and Jacobs was happy with the overall performance.
He said: “Fleetwood is a really tough place to come and they have a decent record over the past couple of years.
“We knew it was going to be a battle, so soaking up a bit of a pressure and hitting them on the counter-attack is something we spoke about.
"As soon as we got the goal, we knew we had the defensive capabilities to win the game."
“The conditions, the state of the pitch and the weather all made it difficult, but as soon as we got the goal, we knew we had the defensive capabilities to win the game.
“We obviously had some chances in the second half as well and it could have been more convincing, but I felt we deserved the victory.
“It ultimately panned out that they had quite a lot more possession and were trying to build up the play.
“Sitting back wasn’t a game-plan, but more a case of trying to defend well and see where we could go from there.”
The result means that Pompey have not conceded a single goal in any of their past five league fixtures.
Jacobs said: “We’ve had a bit of a break with the matches that were called off because of Covid and also the weather.
“But the clean sheets have been flowing pretty well for us in the league games and long may that continue.”
