Full-back Tom Hateley admits the loss of Jamie Murphy would be "a massive blow" for Motherwell.
Murphy is out of contract at the end of the season and has been linked with a move to Rangers.
Hateley would love to see the Fir Park side retain the services of the striker but expects his team-mate to be in demand.
Speaking ahead of Tuesday night's game against Dundee United, he said: "He's a top player for us and has been for a number of years now. He's coming towards the end of his contract and he's going to attract attention, whether it's from Rangers or down south or wherever.
"It's pretty inevitable that people will be interested in him. He's been at the top of his game and it would be a massive blow for us but it's just part and parcel of football.
"If the club can keep hold of him, I'm sure they will do their best to do that."
Meanwhile, captain Jon Daly hopes Dundee United can defeat Motherwell and build momentum for the busy Christmas period.
Victory for United at Tannadice will see the hosts climb above Well in the Clydesdale Bank Premier League table.
"It's always a good game and a tough game when we play Motherwell," Daly said. "We've got two fairly similar squads; two good sides. It's normally a good game of football and hopefully we can come out on top.
"It's getting towards a busy schedule coming up to Christmas now. It's a good time to start putting a bit of a run together, starting winning games. If we can get ahead of them now, with the game in-hand as well, it will be important for us to kick on coming up to Christmas."
