Pompey are closing in on a double swoop to boost their threadbare squad.
Defender Sam Sodje is training with the Blues ahead of making a switch to Fratton Park.
And caretaker boss Guy Whttingham is eyeing a loan move for Sunderland midfielder Adam Reed.
Sodje, 33, has been without a club since leaving Notts County in the summer.
But the powerful defender has impressed Whittingham and Andy Awford after linking up with the rest of the Pompey squad.
And a move for Reed could be on the cards, with the 21-year-old looking to pick up first team experience.
Reed has already had loan spells at Bradford, Leyton Orient and Brentford in his young career, with Pompey now expected to be his next port of call.
