Sean Raggett has already been involved in a couple of past promotion pushes during his time at Pompey.
They did not end well, but the defender admits that the current squad are better equipped to get the job done.
He is not getting carried away, though, with plenty of work still to be done if the Blues are to enjoy success.
So after a narrow weekend win at Carlisle, the defender is only concentrating on facing Cambridge on Tuesday evening.
Raggett said: “We’re in a really good place after that sticky patch just after Christmas – we’ve bounced back well.
“It’s been four wins and a draw from the past five games, with four of them away from home, and we’re on a good little run now.
“Getting a comfortable victory against Northampton was nice, but then you also need to go to places like Carlisle and grind out a result.
"But – and I know it’s a bit of a cliché – we do just take it one game at a time, particularly because of the strength of the sides just below us."
“In previous years when we’ve gone top of the table, we’ve dropped off a bit by this stage of the season.
“We’re right there at the moment, though, and it’s the strongest position we’ve found ourselves in since I’ve been at the club.
“But – and I know it’s a bit of a cliché – we do just take it one game at a time, particularly because of the strength of the sides just below us.
“It makes us feel like we have go out there and win every single time, otherwise they can catch up to you.”
January signing Tom McIntyre took Raggett’s spot in the starting line-up for the last home game against Northampton.
But the newcomer suffered an ankle injury after just 52 minutes to give the man he replaced a swift return.
Raggett said: “It’s tough to be left out, but that’s football. I was obviously disappointed and just had to make sure I was ready for when the chance came back around.
“It’s unfortunate for Tom to suffer quite a bad injury, which you don’t want to see. You’ve got to keep yourself focused, though.”
