Trialist Anton Peterlin could earn a contract with Plymouth after impressing manager Peter Reid.
The former Everton midfielder has been with the Pilgrims since the start of pre-season and has so far featured in three friendlies.
Agent Barry McLean, who represents the 23-year-old, has previously indicated his client was closing in on a move to the club.
And Reid told The Herald: "He has done well. I thought he did ever so well in the game against (NAC) Breda. We started him at right-back and moved him to the right-side of midfield.
"He ended up in the centre of midfield and he's a boy with plenty of energy who doesn't give the ball away. He has acquitted himself really well. The lad has got a chance."
Meanwhile, Reda Johnson (groin) and Bondz N'Gala (ankle) are recovering from recent injuries.
Reid is confident they will return soon, adding: "The two lads have got little niggles but they aren't serious ones."
