Haji Mnoga has signed his first professional contract with Pompey.
The 17-year-old academy defender has put pen to paper on an 18-month deal, with the club holding an option for a further year
Mnoga – who has represented England at under-17 level – made three appearances for the first team in last season’s EFL Trophy.
He was part of a back-line that kept clean sheets in victories over Crawley and Peterborough, and has recently recovered from a foot injury.
“I’m over the moon,” said Mnoga. “Every boy dreams of getting a professional contract with their hometown club. It’s an early Christmas present for me.
“I like getting forward from right-back, although I can also play in the centre. I always get stuck in and work my socks off.”
"I’m over the moon. Every boy dreams of getting a professional contract with their hometown club."
Academy manager Mark Kelly said: “It’s very good news for Haji. He’s been part of the club for a long time and it’s a proud occasion for him and his family.
“There’s a lot of developing for him to do now, so he needs to get his head down and keep working hard to push on.
“Haji’s a local boy and now he’ll be looking to mature and find consistent performances, so he can make the next step.
“He’s a strong and tenacious boy. He’ll get up and down the pitch and is very physical, while he can use the ball well.”
Blues boss Kenny Jackett said: “The challenge for him now is to try to push into the team and he’s shown plenty of promise so far.
“He’s a powerful lad and has plenty of pace – he’s got a lot of qualities and I’m sure he’ll get opportunities for us.”
