John Mousinho has dismissed Charlton’s excellent recent record at Fratton Park as an irrelevance.
The Londoners have won on each of their past seven visits to Pompey’s patch – a run that stretches back to 2005.
So the omens certainly look good for them ahead of Saturday’s League One contest on the south coast.
But Mousinho does not believe what has happened in the past will affect the latest meeting between the sides.
The Blues boss said: “I wasn’t aware of that history, although I remember watching the game against Charlton last season not long before I arrived here.
“That definitely wasn’t the best, but it’s two completely different sides now, with two different head coaches.
“So hopefully we can banish all those records to the history books and, to be honest, it’s totally irrelevant to this game.
“I think it will be an exciting match against a side who have been playing some nice football since Michael Appleton came in.
“He’s got a reputation as an excellent coach for good reason and his sides have always played attacking football.
“They’re a side that underachieved at the start of the season, but are now picking up some positive results.
"Hopefully we can banish all those records to the history books and, to be honest, it’s totally irrelevant to this game."
“I’m sure the atmosphere will be right up there on Saturday and it’ll be great to be back at a sold out Fratton Park.”
Abu Kamara revealed that a demand from his boss to run more was behind his midweek winner at Leyton Orient.
Mousinho explained: “I’ve never got a problem with his work-rate and he always puts in a really good shift off the ball.
“What we want Abu to do is use his athleticism because he’s probably the second quickest player in the squad after Gavin Whyte.
“I don’t see anyone else at this level living with him in terms of that raw pace when he gets going, so when the space is tight we want him to receive the ball on the run.
“He’s got really good quality in front of goal and has scored three times already, but we want to see more of it.
“Once we get him going on the side and not wanting the ball to feet all the time, we’ve got a really useful player.”
Mousinho is still waiting to learn the extent of Regan Poole’s injury after he limped from the pitch at Chesterfield last Sunday.
He said: “We haven’t had the results yet, so we’re waiting on those. He’s unlikely to play for us on Saturday.
“Tino Anjorin had his scan and it was probably slightly worse than we thought, with a hamstring tear. We just have to tread carefully and are in communication with Chelsea.
“Marlon Pack is in the running again for Saturday and has fully trained this week, so is certainly in contention.”
