Danny Cowley is well aware of the areas where Pompey are failing at the moment.
Successive defeats to Rotherham and Ipswich have seen them drop to 17th in the League One standings.
But there were bright moments in both of those matches – and also in previous contests – that were not built upon.
So Cowley is looking for a more consistent display when he takes his troops to Accrington this weekend.
The Blues boss said: “We’re clear on the reasons why we’ve come up a little bit short and it’s not just one thing, so we’re working hard to resolve that.
“There have been injuries to our centre-halves, losing both Clark Robertson and Paul Downing, while Connor Ogilvie has also been out.
“That’s meant we’ve had to adapt and I think any lower league club would suffer in those circumstances.
“No doubt people will question tactics – and people have every right to do so with the disappointing run we’ve been on.
“With a back three, we performed well against Plymouth, who are now top of the league, and would have won that game at Charlton nine times out of 10.
"If it was just tactical, we wouldn’t have had those periods of dominance in games – our weakness has been not sustaining that or reacting well enough when things go against us."
“Then we beat Sunderland 4-0 and were more than competitive for 55 minutes at Rotherham and 40 minutes against Ipswich.
“If it was just tactical, we wouldn’t have had those periods of dominance in games – our weakness has been not sustaining that or reacting well enough when things go against us.
“Certainly in the past two games it has been nowhere near where it needs to be, so we have to be aware of that.
“We’ve tried to learn from Tuesday and then draw a line under it, which you have to do when the games come thick and fast.
“It’s not about talk, it’s about actions. We have to make sure they are louder than our words on Saturday.”
Pompey visit the Crown Ground to face a Stanley side who sit in 10th position and are highly rated by Cowley.
He said: “We understand the challenges that Accrington will bring and have so much respect for John Coleman and his staff.
“Year on year they’re able to build teams that are extremely competitive and allow them to punch above their weight.
“They’re a very powerful team with some of the best players in this division – there’s no doubt about that.
“We’re going to have to arrive with a mindset and a physicality that enables us to perform to our best.”
