Victories in pre-season do not necessarily translate into success when the competitive fixtures begin.
But Kenny Jackett was still pleased to see his squad get their run of friendlies of to a winning start with a convincing triumph at Cork.
The reigning Irish Premier Division champions were beaten 4-1, largely thanks to a dominant first half display from their League One opponents.
A Christian Burgess header and Jamal Lowe finish gave Pompey a comfortable interval lead and Jackett then changed his entire side.
Cork managed to reduce the deficit, only for Conor Chaplin to show his eye for goal by adding a brace.
And with 22 players getting time out on the pitch, Jackett believed the trip to Turner’s Cross was a useful exercise.
The Blues boss said: “It’s always good to win games and you want to build up that habit throughout pre-season because it helps your confidence.
“There’s also the spirit and determination it can develop as we head towards that first competitive game.
"It’s always good to win games and you want to build up that habit throughout pre-season because it helps your confidence."
“It’s the start of our second week back in training and it was useful to give everyone a run-out against Cork.
“You’re looking for match fitness, to build up an understanding and to let the new lads integrate with the ones who were already here.
“We’ve got to make sure they’re welcomed in – on and off the pitch – and all know what their roles are.
“We had some very young boys on the pitch during the second half, although some of them are still quite experienced.
“I certainly felt we weren’t as balanced after the break, but some people were used out of position, which didn’t exactly help.
“They still put the work in, though, and Conor added two very good goals to contribute to a positive evening.”
There might not be further fixtures during Pompey’s stay in Ireland, but that does not mean the players can relax.
Jackett said: “There will be double sessions for the rest of our week in Ireland as we build towards the Havant & Waterlooville match on Saturday.
“We want to really make sure those fitness levels stay high. We’ve got good facilities here and intend to use them.”
