Pompey have been told to go for the jugular at Leeds.
The Blues go to Elland Road today looking to bounce back from a last-ditch defeat against Peterborough on Tuesday night.
Pompey battered Posh in the second half at Fratton Park before being caught by an injury-time sucker-punch in a 3-2 defeat.
Steve Cotterill is not expecting to go on the back foot now, despite his side facing a tough clash at Leeds.
The Blues manager said: ‘It might well be an open game.
‘We are not going up there to sit back. We want to go up there and have a game.
‘It’s disappointing to lose and lose in the manner we did on Tuesday. We were dominant against a good Peterborough team.
‘If we play like we played the other night, we’ll be looking to gain three points. That’s what we’ll be aiming to do.’
Cotterill has no qualms about calling on Erik Huseklepp and Jamie Ashdown at Leeds.
Both men made crucial mistakes on Tuesday as Ashdown let the ball squirm through his grasp for the opener.
Huseklepp was then left crestfallen when his own goal at the death gave Peterborough the win.
Cotterill said: ‘I’ve spoken with Erik. I haven’t seen Jamie about it.
‘What can you say which makes it better?
‘They both made mistakes. It happens.
‘You could be more technical with them and ask questions.
‘Until you’ve been there in the arena you won’t know what it’s like. You don’t want to make the mistakes.
‘We win together and lose together. That’s what happens here. The support will help them.
‘Who’s to say they won’t be the heroes at Leeds?’
