The 22-year-old made the most of an offer to train with the Blues by impressing the Fratton Park coaching staff sufficiently enough to be rewarded with a deal until mid-January.
Pompey turned to the player after learning that Tino Anjorin will likely be out until the new year with a hamstring injury. His signing also comes at a time when Anthony Scully continues his rehab after knee surgery.
At present, attack-minded duo Scully and Anjorin are joined in the Blues treatment room by Regan Poole, Connor Ogilvie and Josh Dockerill.
Marlon Pack and Tom Lowery are closing in on their returns to first-team action. But if Pompey are prepared to delve into the free agents market to help maintain their lead at the top of League One, it begs the question – what other freebees are waiting to be snapped up if the need arose again?
Here’s 12 current out-of-work footballers who are no doubt waiting for the phone to ring to be invited back to the game.
9. Tarique Fosu-Henry - midfield/right-back
His contract at Brentford expired in the summer and so far no club has signed him. The 28-year-old former Charlton, Oxford, Stoke and Rotherham player has played more than 100 games in the Championship. Photo: Nathan Stirk
10. Matt Macey - goalkeeper
You have to wonder if the giant stopper regrets turning down an offer to remain at Pompey in order to remain at Luton, who subsequently released him in the summer - after the Blues had turned to Will Norris. Photo: Jason Brown
11. Luke Freeman - attacking midfielder
Released by Luton Town in the summer. Played for various clubs in the Championship, like QPR, Bristol City and Sheffield United. The attacking midfielder is an interesting option for any club to consider. Photo: Ryan Hiscott
12. Steven Caulker - centre-back
The 31-year-old has been without a club since leaving Wigan Athletic. The defender has bags of experience and counts Spurs, Liverpool and QPR among his list of ex-clubs. Photo: CHARLY TRIBALLEAU
