Alassane N’Diaye will remain on trial with Pompey with a view to joining the club at a later date.
But the other triallists who trained with the Blues today will not be offered deals.
As revealed by The News, towering midfielder N’Diaye has linked up with Pompey hoping to impress.
The former Crystal Palace man was one of a number of free agents training with the club on their final day before moving out of their Eastleigh base.
Also in attendance was Aman Vermn, a 26-year-old striker formerly with Leicester City, and ex-England under-18 winger Tristan Plummer.
However, the duo will not be staying on.
There was also the surprise sight of Brian Howard training with Pompey today.
The former skipper, who was released earlier this month, is training with the club as he makes his comeback following a hernia operation.
But there are no plans for him to return to the Blues.
