Only two teams in League One have conceded fewer goals than Pompey so far this term.
So Craig MacGillivray can understandably be frustrated about the fact they have kept just one clean sheet in his past seven appearances.
A 1-0 victory at Coventry is the sole time they have shut the opposition out in the league since Plymouth were comfortably beaten at the start of September.
But with teams seemingly saving their screamers for contests with the Blues, MacGillivray knows there is not a lot they could have done differently.
The goalkeeper said: “We have looked pretty solid in the past few games and it just seems that very good goals keep getting scored against us.
“I was annoyed by the one at Wimbledon because their lad isn’t known for getting them from outside the box and he hit it with his weak foot!
"We have looked pretty solid in the past few games and it just seems that very good goals keep getting scored against us."
“There are little things we can obviously do to try to prevent that from happening, but it just is what it is.
“We’re working hard and still conceding a minimal amount, while the most important thing is that we’re winning games.”
Now Pompey will look to continue their reign at the League One summit when they host Fleetwood on Saturday.
MacGillivray said: “They’ve won the last two in the league, have beaten Doncaster and only conceded two goals away from home this season.
“It’s another side that are doing very well and they’re currently just outside the play-offs, so it’s going to be tough.
“Everyone knows about the likes of Paddy Madden and Ched Evans up front, but we’re looking forward to that test.
“We’ll have to make sure that we’re bang at it on Saturday if we want to come away with all three points.
“We’re just over a quarter of the way through the season and there’s still a long way to go, so we’re just taking it one game at a time.”
