Guy Whittingham insisted Pompey only had themselves to blame after throwing away a 2-1 lead to go down to a gut-wrenching 3-2 loss at Brentford.
The Blues caretaker boss saw his men grab the lead just before the hour mark as Shaun Cooper drilled home a low shot after David Connolly had cancelled out Bradley Wright-Phillips’ opener.
But with just five minutes remaining, Wright-Phillips tucked away his second of the game, before Clayton Donaldson buried the winner to complete an extraordinary turnaround within the space of a minute or so.
Whittingham, however, refused to look for a bad luck story and insisted his men should have coped with the Brentford attack better.
‘It’s professional football and if you can’t keep a lead with 10 minutes to go, then that happens,’ said Whittingham.
‘Up to that point, we defended magnificently well and then we gave the ball away too much.
‘Instead of forcing them to try to get it off us, we let them have it too easily.
‘It might be a bit of being in that position and not being able to see it out.
‘We had enough experienced players on the pitch to do that.
‘We dealt with the majority of things they threw at us.
‘It’s really disappointing. They are going for promotion and we gave them a real game.’
