Already, the Blues head coach has recruited 12 new signings in what has been a major squad overhaul.
However, if Cowley is to have his way there will still be more incomings, which could be factored by getting players out of PO4, over the next week.
So, with more anticipated transfer business for Pompey, we posed the question to the Fratton faithful who they’d realistically like to see arrive before the window closes.
And here’s who the Blues supporters on social media want to arrive in the coming days...
9. Danny Hylton (Luton)
The striker could be a player the Hatters would allow to leave as they look to trim their playing squad. Has scored 58 times in 148 matches over a five-year period at Kenilworth Road. Yet to feature for Luton at all this season Photo: Julian Finney
10. Ben Cottrell (Arsenal)
Has come through the ranks at the Premier League Gunners, making his first-team bow in a Europa League match against Dundalk last season. Arsenal are looking to offload the midfielder to aid his development with minutes on loan in the Football League Photo: James Chance
11. Omar Bogle (Doncaster)
Surplus to requirements at League One Donny, with Richie Wellens keen to offload the striker. Has turned down two reported moves to League Two clubs. Scored four goals in 14 matches on loan at Pompey in the 2018-19 season Photo: Daniel Chesterton
12. Matty Taylor (Oxford United)
Scored 19 goals in 52 appearances for the U's last term as they reached the League One play-offs before semi-final defeat to Blackpool. Played in all four of Oxford's League One games this season, scoring once. Would likely take a sizeable figure for Oxford to even consider selling. Could do a swap deal with reported U's target Ellis Harrison! Photo: Stu Forster
