Shorey is linked heavily with a move to Portsmouth, Kitson to Fulham for £2.5m and Harper to the North East and Middlesbrough.
Glenn Little, already at Portsmouth after a move earlier this month is urging his pal to join him on the South coast.
"Nicky is my best mate so of course I am going to say good things about him. But I would love to see him sign for Portsmouth as well - and they would also be getting a very good player," he said.
"He lives just round the corner from me on the outskirts of Reading and we are always going out together. We are always round each others' houses and he was my room partner at Reading.
"I know a few of the Pompey players but it would be fantastic to have my best mate in the dressing room as well down here. I'd love it.
"Reading have already got the hump with me for leaving so I am not going to try to upset people saying he should go and sign for so and so. But at the end of the day I want what's best for him and he should follow me down here.
"He wants to be in the Premier League, he's an England player and has been the best left-back in the Championship for a number of years.
"Reading won't want him to go on the cheap but it would be great if I could see more of him - so I want him to come to Portsmouth as well."
