A host of club are ready to test Rangers' resolve over Madjid Bougherra before the World Cup, skysports.com understands.
Liverpool are the latest club to join the hunt for the Algerian - who looks set to be sold by financially strapped Rangers in the summer.
A host of English clubs, as well as teams from Spain and Germany, are looking at the 27-year-old - who has been with Rangers since 2008.
Bougherra has already insisted he is more than happy at Ibrox, but The Gers look set to sell.
And skysports.com understands that Bougherra's camp are keen for his future to be resolved before the World Cup finals.
"I'm very happy here," said Bougherra at the SPL season awards on Sunday.
"If I stay, I'm very happy and if I have to leave one day, that's life.
"In both cases, I'm happy."
Bougherra will miss the midweek Old Firm clash with Celtic as he looks ahead to the World Cup with Algeria.
"It's better to have some games in the legs," he said.
"But, at this stage, you have to be very careful about taking any risk because the job is done: we have won the title.
"If you have something bad in your body, don't take a risk because the big thing is coming: the World Cup."
Bougherra also hailed Walter Smith, who was crowned SPL Manager of the Year.
"When I came to Rangers, my life changed," he said.
"Everything is fantastic. I learned a mentality, I progressed.
"I'm this player because Rangers gave me the opportunity.
"He gives me the confidence that, on the pitch, I can do what I want.
"Where I was before, some gaffers didn't want me to run. I need this to come into the game.
"If I've done well this season, it is because he gave me this confidence."
