Boss criticises lack of potency
The Blues have now kept clean sheets in each of their last three games.
But Richie Barker wants to see an improvement at the other end of the pitch following a goalless draw with Cheltenham.
Pompey did not create too many chances, although Wes Fogden’s shot was cleared off the line at the death.
And Barker was critical of his side’s first half display against the Robins, despite another solid defensive display.
The Blues boss said: “We were going though the motions to a certain extent.
“In the second half it only looked like one team were going to win it, but yet again we’ve not started well enough.
“We were wasteful in the final third and I don’t think we worked their goalkeeper enough.
“I can’t keep coming out and talking about another clean sheet. They’re great and it’s something to build on, but people come to see goals.
“The back four did their job and, as a whole group, we’re doing the right things defensively.
“The record at that end is great, but the goalscoring record needs to be improved.”
Barker also revealed that Daniel Alfei and Andy Barcham missed the game with injuries.
He said: “Dan picked up a hamstring problem while he was away with Wales, while Andy got a knock in training on Friday.”
