Academy youngster Chinedu Vine has left Pompey by mutual consent.
Now the striker is hoping to get his career back on track in Portugal with new club CD Feirense.
The 18-year-old joined Fratton Park in the summer of 2010 from Home Farm.
His arrival was part of an agreement for the Irish club to send over their most promising players. Yet Vine subsequently struggled to make an impact at Pompey.
He amassed just five appearances last season for Andy Awford’s side, all as a substitute.
When many of Vine’s team-mates were asked to train with Michael Appleton’s squad, the youngster was not invited.
Under terms of his arrival from Dublin-based Home Farm, he was entitled to a first-year professional deal.
However, it was agreed he should leave Fratton Park early.
Now Vine has joined Portuguese outfit CD Feirense following a successful trial there towards the end of last season.
Feirense were relegated from the Primeira Liga last season after finishing 15th. Based in the city of Santa Maria da Feira, they will play in the Liga de Honra next term.
Vine joins the likes of James Jennings and Matt Gledhill in leaving Pompey this summer.
In addition, Carl Walshe, who arrived from Home Farm a year earlier, has left.
Walshe has since returned to his native Ireland.
Blues administrator Trevor Birch said: ‘We have come to an agreement with some of the youngsters to leave the club.’
