Kenny Jackett says his players do not need lifting ahead of their midweek trip to Walsall.
Pompey were narrowly beaten at promotion rivals Charlton at the weekend, but remain fourth in the League One standings.
Prior to that they had defeated Bury to secure a trip to Wembley and then enjoyed a 5-1 rout over Bradford.
Jackett knows his side have to improve on their performance at The Valley, however, and believes they can do that on Tuesday.
The Blues boss said: “To put a run together we need to play with confidence, score goals and keep clean sheets – we’re always working away on that.
“We certainly are capable of that because with the crowd we have at Pompey, we can build some momentum.
"It leaves us with a lot to play for this season in two competitions, so I don’t think the players need a lift."
“There’s a balance for us to find in and out of possession, with the number of goals we’ve conceded away from home getting higher and seeing us drop out of the top two.
“But we had a good week by getting through a semi-final and then securing probably our best win of the campaign against Bradford.
“It leaves us with a lot to play for this season in two competitions, so I don’t think the players need a lift.
“They need to learn from the Charlton match, but now focus on facing Walsall and do everything we can to bounce back.
“It will be a different type of game and we’re pleased we’ve got another one within a few days of Saturday.
“We’ll respect Walsall’s strengths, but are more concerned with making sure that we can get back to our best.”
Jackett has an extra attacking option for their clash with a Saddlers outfit currently down in 16th position.
He said: “We have no new injuries from the Charlton game, but Omar Bogle will be added to the squad after his hamstring problem, which is good news.
“Bryn Morris and Andy Cannon aren’t fit and they won’t make Saturday, but we’re hopeful they might be available after Scunthorpe.”
