Steve Cotterill shrugged off a bleak 48 hours and vowed to keep fighting on.
Pompey suffered a harsh 2-0 defeat at Championship leaders QPR last night.
It completed a desperately disappointing few days for the Blues, who failed to sign any players during Monday’s transfer deadline day.
Pompey have now gone nine matches without a win in all competitions.
But Cotterill was hugely encouraged by last night’s showing, insisting the visitors were the better side.
And despite talk the club’s woes would force the Blues boss to quit, he is remaining upbeat despite being hamstrung by tight finances off the pitch and bad luck on it.
Cotterill said: ‘We’re fine. We saw that in the performance last night.
‘I thought we might have had someone in on deadline day, I have to say. I thought maybe someone would have come in.
‘I can sit and sulk about it all I like but I don’t think that is going to help the situation we are in now.
‘Since I came through the door here it has been a tough job and it has been frustrating. But we have a really, really good set of fans. I think I have struck up a rapport with them and I think they know what type of job I have got.
‘And I have struck up a rapport with the lads in the dressing room.
‘Last night I thought we were the better team. I thought we were the better team in the first half and I thought we were the better team in the second half.
‘We are disappointed with the result, for sure, but we are fine.’
Jamie Ashdown’s howler gifted Neil Warnock’s side a 59th-minute lead through Adel Taarabt after they struggled to break down the Blues.
Clint Hill then added a second on 73 minutes, much to the relief of the often-frustrated home support.
Cotterill felt the scoreline wasn’t a true reflection of Pompey’s encouraging display.
He added: ‘Jamie made a mistake and the second goal was after we missed a header and lost a marker in the box, which we don’t normally do.
‘The two goals were the only difference.
‘I think with the two goals everybody will think QPR were probably the better team in the second half but I don’t think that.
‘QPR will get promoted this season. The squad is strong enough, the manager has seen and done it before, ably assisted by Keith Curle.
‘They have a great bunch of lads, I think, with a really good spirit among them.
‘I think they will get promoted but we’ve gone there and been the better team.’
