Pompey have been challenged to use their first League One victory as a springboard to success.
The Blues take on Walsall at Fratton Park looking for back-to-back league wins as they enter a period of three games in eight days.
Michael Appleton feels his team will be taking on a fearless young side who like to play an attractive brand of football.
But he believes his team are high on confidence after Ashley Harris, Luke Rodgers and Izale McLeod scored in the 3-0 victory over Crawley.
And that is something the Pompey manager wants his men to cash in on.
Appleton said: ‘We have needed a catalyst to give us a lift.
‘The place has been low at times with the distractions off the field.
‘But they’ve done that well over the past five or six days.
‘It’s important to use that Crawley result as a springboard to win more games.
‘We’ve got three games this week and things can change very quickly. I’ve explained that to the players.’
Appleton believes tomorrow’s clash has the ingredients needed for an entertaining game.
Dean Smith’s side put MK Dons to the sword last weekend to cement an encouraging start to the campaign.
Appleton said: ‘Walsall are an example of when people try to write teams off.
‘They had a fantastic result against MK Dons last week and there have been others, too.
‘They’ll come here full of confidence and we’ll go into the game full of confidence.
‘They are a young side and it shows in their game.
‘They have a group of players who play without fear and enjoy the game. That can be dangerous.’
