Andy Awford launched a scathing attacking on Pompey’s first-half performance after seeing them share a 2-2 draw with Wycombe.
Anthony Stewart’s goal, four minutes into stoppage time, broke the hearts of the Blues after they looked set to cap an outstanding second half with a victory.
A wretched opening 45 minutes saw the team booed off and one goal behind through Matt McClure’s 22nd-minute strike.
The response was magnificent, with Andy Barcham and substitute Patrick Agyemang netting while David Connolly missed a penalty.
Yet they still ended up with a draw with that last-gasp leveller and caretaker boss Awford was seething with that first-half showing.
He said: ‘The first half wasn’t good enough. What was said will remain private but it shouldn’t take me to go in and say what I said.
‘Even if we’d had 10-15 per cent better performance in that first half we win the game because they don’t score and in the second half I can’t fault them in terms of effort tempo and application.
‘I don’t get – and I’ve told them this – how it can be so different between the first and the second half?
‘They were rabbits in the headlight in the first half. It’s an intimidating place to play but get used to it lads, you play for Portsmouth, it’s not going to change.
‘To be fair to them they went out second half and what a performance that was – but the first half wasn’t good enough, simple.’
