Manchester United have agreed to sell Angel Di Maria to Paris St Germain for 63million euros.
Manager Stuart McCall believes there is only a "slim possibility" that Darren Randolph will still be in goal for Motherwell next season.
The 25-year-old former Charlton goalkeeper has been a key part of the Fir Park side since moving north of the border on a free transfer in 2010.
However, his three-year deal expires at the end of the season and McCall is bracing himself for the Irishman's departure.
Ahead of the Clydesdale Bank Premier League clash with Dundee United at Tannadice, the Steelmen's boss said: "I would be absolutely delighted if we managed to keep Darren but I think it is a slim possibility.
"There is a strong possibility that Darren Randolph will move on.
"Darren has been outstanding for us and if I was managing in the Championship now I would go for him straight away - and that's not me trying to off-load him.
"I have been surprised that we have not had offers for him over the 18 months.
"He is not only an outstanding goalkeeper, he is a really good guy, he is composed, he gets about his job, never lets us down - you would think I am his agent but I am not.
"But I would be extremely surprised if he didn't have very good options."
Asked about the report claiming Motherwell were looking at St Mirren keeper Craig Samson as a replacement, McCall said: "We will be looking for someone to vie with Lee Hollis.
"So it is certainly an area we will need to look to get competition in.
"I don't know where this Samson thing came from.
"He is a good goalkeeper but I have had no contact with anyone regarding him."
When it was suggested to Randolph that he would definitely be leaving the club at the end of the season, the keeper said: "Am I? We have another five games left and I am the same as the other players out of contract."
Randolph admitted that regular football - as well as which of his out-of-contract team-mates would be leaving - is likely to influence any decision he makes.
He said: "Wherever it, is I want to play. That's why everyone is in football, to play.
"So wherever I can do that I will be there.
"If we could keep the core of the team then I suppose it will make it easier to decide I suppose."
McCall insists United will not be too affected by their 4-3 extra-time William Hill Scottish Cup semi-final defeat by Celtic at Hampden Park last week.
He said: "I think they will be good. They were terrific (against Celtic) and they on their day they are as good as anything in this league.
"But I'm sure they will be looking at our forwards, James McFadden, Chris Humphrey, Henrik Ojamaa, Michael Higdon and players like Nicky Law and Keith Lasley, so it has the makings of an open game."
