What late, late deadline signing will give Portsmouth as ex-Leyton Orient man arrives from Huddersfield Town

The attacking talent joined as a late deadline-day arrival, on a season-long loan from Championship Huddersfield - where Cowley worked with him.

The 23-year-old is the 12th signing of what Cowley believes has been a very successful transfer window for the Blues.

The Pompey boss believes Koroma will offer attacking versatility as well as injecting pace into his front line and providing set-piece quality.

Cowley told the club’s official site: ‘Josh is a boy we obviously know very well and he’s had an excellent career to date, but is still very young.

‘He started at Leyton Orient and did brilliantly there under the late Justin Edinburgh, playing a big part in helping them get promoted back into the Football League.

‘He’s a boy who can play in a multitude of positions – on the left, on the right or as a number nine. It gives us real versatility and flexibility at the top end of the pitch.

‘We’re excited to have him with us and it’s the final piece of what’s been a really positive transfer window for this football club.

‘Josh has real pace and power. He loves to dribble, while he’s a clean striker of the ball – inside and outside of the box – and takes set-pieces.

A slow start to the window which generated criticism from some supporters has accelerated quickly with a dozen players supplementing Cowley’s squad.

Koroma will bolster an attack which now includes Joe Pigott, Colby Bishop and Dane Scarlett with Owen Dale arriving out wide.

Elsewhere, the likes of Marlon Pack, Joe Rafferty and Michael Morrison have come in to give Pompey squad added depth and quality.

Cowley added: ‘We’re excited to have Josh with us and it’s the final piece of what’s been a really positive transfer window for this football club.’
