Pompey could have no complaints over their last-gasp loss at Cardiff.
Michael Appleton reckons dozy defending was a key factor in the 3-2 loss against the high-fliers on Saturday.
Craig Conway’s injury-time winner did the damage for Malky Mackay’s side.
Pompey were caught napping from a quick free-kick – a similar story to the home side’s second from a throw-in.
Appleton said: ‘I’m frustrated and disappointed we switched off from a quick free-kick.
‘We switched off for their goals – it was a quick throw and a quick free-kick.
‘Every point is crucial in our position now. The momentum swung in our favour a little and we were in a good position.
‘But we can have no complaints with the result.
Appleton was loathe to blame his bedraggled squad, though.
He said: ‘I don’t want to make excuses but I’m asking the players to do things now I shouldn’t.
‘We have 13 fit outfield players and it isn’t really going to get any better.’
