Pompey assistant boss Gary Waddock admitted it was a frustrating evening as the Blues failed to beat Cheltenham Town.
The relegation strugglers left Fratton Park with a 2-2 draw following a disappointing display from the home side.
Matt Tubbs’ 17th-minute opener was cancelled out by Eliot Richards, only for the Robins to then take the lead in the 23rd minute.
In-form Ryan Taylor grabbed the equaliser just before the half-time, with neither side able to add to their tallies after the break.
It was a draw which did neither team good in their contrasting ambitions, which in Pompey’s case leaves them eight points adrift of the play-offs with nine games remaining.
Waddock said: ‘It was a frustrating evening.
‘This was a game we were looking to win being a home match.
‘You have to give credit to Cheltenham for the way they set themselves up but we are frustrated and disappointed with the outcome of the game.
‘We should have dealt with their two goals better, as well as taking the lead then being pegged back so quickly.
‘You don’t point the finger at any one individual.
We are frustrated and disappointed with the outcome of the game.Gary Waddock
‘Paul Robinson isn’t in the team, he has picked up an injury and, a player of that experience and quality, any team would miss him.’
