This week alone, three names have been tipped with a switch to Fratton Park as speculation continues to increase ahead of the summer.
The Blues are expected to be busy in the market, with 9-10 new faces set to arrive through the doors at PO4.
That will be part of John Mousinho’s squad overhaul as he looks to build his promotion-contending side.
With so many names already reportedly on Pompey’s radar, we’ve taken a look at every name who has been linked with a switch ahead of the window, which opens next week, and their current situations.
5. Lee Bonis
According to the Daily Mail in April, Pompey were one of four EFL sides chasing the Irish striker, who is valued at £300,000 by Larne. Following the reports, however, Mousinho was quick to rule out a move - stating he was unaware of the 17-goal front man. Photo: Pacemaker Desmond Loughery
6. Matthew Pennington
A number of various sources claimed Pennington was on the radar of the Blues as they looked to improve their central defensive options. Yet, he was another who was quickly ruled out soon after the report emerged. Photo: Pete Norton
7. Di'Shon Bernard
After a strong loan spell at Fratton Park during the second half of the campaign, Mousinho revealed he would be keen to sign the defender this summer. The possibility of a swoop for the Manchester United man will become clearer when the Red Devils release their retained list. Photo: Jason Brown
8. Ruben Rodrigues
The talented Notts County ace will be on the move in the window and Football Insider claimed the Blues were interested in the attacking midfielder. Less than a day after the link emerged, The News quickly understood a deal is not in the works for the 26-year-old. Photo: Eddie Keogh
