Kenny Jackett is encouraging his side to engage in some more target practice during matches.
Pompey had just a couple of shots on target during Tuesday night’s narrow defeat at high-flying Coventry.
That brought to an end a run of nine successive victories that reinvigorated promotion hopes among the Fratton faithful.
Now Jackett wants to see them working hard to undo a Shrewsbury outfit who have slipped down the standings in recent weeks.
The Blues boss said: “You will see a lot of tight games at this stage of the season when you’ve already played so many fixtures.
“But for all the periods of dominance we have – and there are times we look a really strong team – we need to get more shots away.
“I think that it’s a combination of tactical play, team selection and also the attitude in your mind.
"As much as you want shots from everywhere, the ones that usually count come from inside the 18-yard box."
"It might be we’re in good wide areas and the ball doesn’t go in or perhaps there aren’t enough people to meet thhose cosses.
“As much as you want shots from everywhere, the ones that usually count come from inside the 18-yard box.
“We’ll look to do that against a Shrewsbury side who have a very good defensive record and look to be a solid unit.
“There are 15 league games remaining for us – which is a big chunk of the season – and I think we can rise to the challenge.
“We’re certainly capable of beating anyone on our day and it’s about making sure we get the details right.”
Storm Dennis could wreak havoc this weekend, with the south coast set to be battered by strong winds and heavy rain.
Jackett said: “It will be the same for both teams and you have to get used to playing in different conditions and on different kinds of pitches.
“We don’t really focus on it too much, but you assess the situation at the time and make sure your attitude overcomes any problems.”
