The Pompey boss felt the 6-0 pre-season win at the Hawks was the perfect exercise in gearing up for the new campaign for his team.
The Blues grabbed a string of goals to boost their confidence and were worked hard for 90 minutes by Lee Bradbury’s men.
Jackett said: ‘It was a good pre-season workout.
‘It was good to see so many supporters and a good turnout at a local game.
‘The players played with enthusiasm and it helps us on our way to the season.
‘In terms of performance, it’s a step in the right direction.
‘But we work hard in July to make sure we’re successful in August.’
