Motherwell have offered new contracts to Scotland defender Declan Gallagher, Allan Campbell and Liam Polworth.
Manager Stephen Robinson believes the club have worked hard to keep the trio in North Lanarkshire, but concedes they may be tempted by better offers elsewhere.
He said: ”They’ve all been offered contracts. It’s up to them what they do.
“There is a limit where Motherwell can go to. I don’t have a problem with that, as long as people conduct themselves properly and have humility.
“It’s up to them. We have made our offers and tried very hard. We’ll see where that goes.”
Robinson was speaking to the media ahead of Saturday’s visit to Ibrox.
Motherwell suffered a 5-1 defeat against Rangers at Fir Park in September and lost 4-0 to Steven Gerrard’s side in pre-season.
And Robinson says he will use a different blueprint this weekend, reflecting on a late 2-1 defeat in Govan in October last year.
“The reality is if we go toe-to-toe with Rangers, which we have done on occasions, they inevitably win,” he said.
“You do have to change, I don’t think there’s any shame in that. Most clubs at our level have to change when you play a top team. You have to be a it more defensive minded.
“What we maybe haven’t done in the past is stay in the game long enough and that’s something we will look to change.
“But when we went there the last time we got beaten from a set-play. We set up very well, were strong and organised and gave them a really good game.
“The pre-season game we went out and tried to play and got battered. There are lessons to be learned all the time and you try and take them all the time and come up with a solution.”
