Victories on the road at Rochdale and Coventry ensured that Pompey spirits are still soaring.
But Kenny Jackett knows that a different challenge is in store when Gillingham visit Fratton Park this weekend.
It means the side currently topping the League One table are hosting one in the drop zone, albeit with a game in hand.
Jackett is aware that does not mean an easy encounter, however, and has warned his troops that they will have to adapt.
The Blues boss said: “We’re trying to highlight to the players what they’re doing right – which at the moment is plenty.
“But we’re also looking at how we can improve because each game provides its own unique test and there are some very good sides in this league.
“Going away to Coventry on Tuesday night will be completely different to playing Gillingham at home on Saturday.
"We’re also looking at how we can improve because each game provides its own unique test."
“We have to make sure we continuously realise that and know what is required to overcome our next opponent.
“I’ve got a lot of time for their manager Steve Lovell. They’ll throw a lot of men forward and get people in the box – it’s a strong feature of what they do.
“We’ll have to adapt very quickly and will have to be ready for them because this is a big home game for us in the middle of quite a few away fixtures.
“I think we need to start better at Fratton Park than we have done in recent weeks. We have a great crowd and want to bring that into play as soon as possible.
“We want to put on a good show in front of our own fans and we need to make sure we overcome this test.”
Ronan Curtis is likely to start against the Gills having made a flying start to the season, but will miss the following two games after being called up to the Republic of Ireland squad.
Jackett said: “I’m pleased for Ronan and it justifies his move here. He’s very proud to represent his country and we’ve assembled a squad that can see us through any individual not being available.
“The only person we have missing at the moment is Andre Green, while we expect Dion Donohue to play some part against Crawley next Tuesday.”
