Plymouth boss Paul Sturrock will discuss another move for Craig Cathcart over the next few days after the defender impressed on loan at Home Park.
Cathcart's Manchester United colleague David Gray as well as Blackburn loan duo Paul Gallagher and Alan Judge and Crystal Palace midfielder Carl Fletcher are all options after playing their part in the Pilgrims' survival bid.
"He (Cathcart)'s the one I haven't really had a face-to-face with," Sturrock told The Herald.
"But I have talked to the other four, so I know where they are all coming from.
"Whether we are able to get them back will be in the lap of the Gods. Fletcher is a free agent so I'm sure he will listen to what we have got to offer."
