Ellis Harrison insists there will be no complacency from Pompey in the Emirates FA Cup on Monday night.
The Blues travel to Wetherby Road for a first round contest against a Harrogate Town outfit who compete in the National League.
But the hosts were unbeaten in 10 games prior to last week’s defeat at Eastleigh and are in the division’s play-off places.
An artificial surface is something else for Pompey to contend with, although Harrison is not sure that will affect them.
The striker said: “Those pitches are a lot better these days, although obviously it’s something a bit different for us to get used to.
“But at the end of the day, whoever plays best on the night is going to win the match and we have to make sure it’s us.
"We can’t take anything for granted because that’s when you do get upsets."
“I’ve played against good teams from the Conference when I was there with Bristol Rovers and also in the FA Cup.
“You need to keep the same mentality that you’d have for any other game and look to get the right results.
“We can’t take anything for granted because that’s when you do get upsets. I’m sure they’ll be up for it, but so will we.”
Harrison took – and scored – a penalty that was also coveted by fellow striker in John Marquis in Tuesday night’s league win over Southend.
He said: “I felt confident and the captain (Tom Naylor) told me to take it, so I did. If I’d missed, it would be a different story!
“It was enjoyable playing with John. He was always probing and it was the first time we’d played together in that system, but we linked up well.”
