It was a result that stretched Pompey’s winning run to an impressive eight games.
A 2-0 victory over Southend – with Jamal Lowe adding to a Michael Turner own-goal – also extended their lead at the top of the table to six points.
Things are certainly looking rosy ahead of mouth-watering pre-Christmas clashes with Charlton, Barnsley and Sunderland.
But Kenny Jackett is not one to start getting carried away and knows that there is still plenty of work to do.
The Blues boss said: “I thought we deserved to win and could have scored more because we created a lot of chances.
“Ronan Curtis put the ball into a good area for the first goal and then whipped it in with his right foot for the second. Jamal made a fine run and gave the keeper no chance with his header.
"We have to keep our feet on the ground and remain humble, while trying to continue building confidence."
“There were times when we should have got tighter in the second half, but we still limited them to few – if any – proper chances.
“Jack Whatmough made one excellent block when it looked like we were outnumbered and there wasn’t much else.
“It’s something to build on now for Tuesday night and the players are all in a really good place at the moment.
“But we have to keep our feet on the ground and remain humble, while trying to continue building confidence.
“The crowd were fantastic and to have them and the players bouncing off each other is ideal for me as a manager.”
Gareth Evans came off for Ben Close in the second half, but there are no fitness concerns ahead of Tuesday’s clash with Charlton.
Jackett said: “I just felt we needed a bit more in midfield at that stage of the game and Ben has come on in various matches to keep the ball for us well.
“He should have scored really because Jamal put one on a plate for him, so he’ll be pleased it wasn’t a crucial miss.”
