Fratton Park is known for being a hostile place to visit for away sides.
But even with no fans present inside Pompey’s home, Colby Bishop was taken back by the atmosphere of the ground.
The prolific striker has previously experienced the famous roar from the stands as a player for Accrington.
And after completing his transfer to the south coast, Bishop revealed how excited he will be to pull on the famous Blues shirt.
The 25-year-old said: “I’ve played here before and the atmosphere, along with the size of Pompey, is amazing.
“It’s mesmerizing when you’re in the away team, so I can only imagine what it will be like wearing the Pompey colours. I can’t wait.
“I’m over the moon. The atmosphere of the ground – even when people aren’t here – is great and it was the same walking around town this morning.
"It’s mesmerizing when you’re in the away team, so I can only imagine what it will be like wearing the Pompey colours. I can’t wait."
“It’s so crazy being here and I’m excited. I spoke with the gaffer a lot, but this club speaks for itself really.
“I’ve got nothing but kind words to say about Accrington, who have been excellent to me. I’m hoping that the relationship I had with the fans there can be built here.
“The club holds the same ambition as I have – to push up the leagues – so it’s a great fit and hopefully we can do that.”
Bishop played non-league football before being snapped up by Stanley and believes that has helped his development.
He said: “I used to work as a PE teacher and play part-time. It was busy and made me realise just what you can do.
“Since being in professional football again, I’ve used that time and it’s paid off for me. I’m hoping to get even stronger coming to a club like this.
“I’m used to playing in this league and with the talent I’ll have around me here, I know I’ll get chances and want to put them away.
“Whenever I put the shirt on I’ll work as hard as I can, as well as hopefully scoring goals and helping my team-mates.”
