Pompey have been linked with a move for Liverpool keeper Ryan Fulton.
The Blues and Scottish side Aberdeen both want the 19-year-old, according to the Daily Mail.
Fulton has featured regularly for Liverpool’s under-21 team and as a substitute for the first team.
The Scottish under-21 international is said to be highly thought of at Anfield and signed a contract extension in December.
Brian Murphy remains Pompey’s only experienced keeper at present with Paul Jones and Michael Poke sidelined.
