Rangers have opened discussions about extending the contract of midfielder Maurice Edu.
The 25-year-old United States player moved to Ibrox in 2008 and has 18 months remaining on his five-year deal.
"We've spoken to Lyle Yorks, a smashing lad who represents Maurice, about keeping him here," manager Ally McCoist told the club website.
"I think Maurice's form in the last three or four games has been really, really encouraging."
Edu was the subject of criticism from fans last season but has been an integral part of the side since McCoist took the helm in the summer.
"He's one of these guys who doesn't always catch the eye but if you ask his team-mates about him, they'll say he always gives performances that are helpful to the side," added the manager.
"We've been very pleased with him. The one thing Maurice does do is work extremely hard - he's a real grafter and a workaholic. That's a massive part of his game.
"It has been well documented that we are looking at keeping Kyle Lafferty here and, like him, Maurice has 18 months to go on his current deal.
"It is common knowledge you have to make it be known that you want to extend deals at this stage and that's where we are with both of those players at the moment."
