Pompey have signed Gassan Ahadme on a season-long loan deal from Premier League side Norwich.
The 20-year-old Moroccan forward has recently been training with the club and scored a hat-trick after coming off the bench in the 5-2 friendly win at Havant & Waterlooville.
Blues boss Danny Cowley said: “We’ve seen a lot of Gassan for Norwich U23s – and we liked what we saw.
“But we wanted to have a closer look at him with our own eyes and he’s been excellent for us in training.
“We called him ‘Trialist H’ at Havant & Waterlooville – which made him sound like he was from Line of Duty – but he scored three goals for us.
“He’s a clean finisher and got a couple more in the match we organised at St George’s Park on Friday and then another two at Bristol City.
"I look at the guys in our squad and we need a link player like him at the top end of the pitch to combine with our other forwards."
“Gassan got a really good loan move to Real Oviedo last season. Unfortunately, he picked up a nasty foot infection, but has recovered from that now.
“He brings other people into the game and his movement is incredibly intelligent. He’s really good at finding his own space.
“I look at the guys in our squad and we need a link player like him at the top end of the pitch to combine with our other forwards.
“We’re really pleased to add him to the group and he certainly provides a different option to what we already have, while giving us tactical flexibility.”
Ahadme joined Norwich from Spanish side Gimnastic de Manresa in January 2019 and featured for their under-23 side.
He appeared for the Canaries in an EFL Trophy game at Fratton Park later that year, playing an hour of their 3-1 defeat to Pompey.
