Southampton midfielder Steven Davis has joined Rangers on loan until the end of the season, subject to international clearance.
Davis had been strongly linked with a return to Ibrox, where he won three Scottish titles and League Cups and two Scottish Cups before joining Southampton in 2012.
The 34-year-old will be out of contract at St Mary's in the summer.
"Steven is yet another fantastic addition to our squad, we are delighted to welcome him back to the club," manager Steven Gerrard told Rangers' official website.
"He is vastly experienced at both club and international level and knows the club, the fans and the demands that come with wearing the Rangers jersey very well.
"He has previously captained the club and been captain for his country and Southampton, so we welcome yet another leader into our dressing room."
Director of football Mark Allen said: "Everyone at the club welcomes Steven back to Rangers.
"He has been on our radar for some time and becomes the fourth transfer that we have confirmed this window already.
"We are delighted that he will be able to join his teammates and get started straight away."
A statement from Davis himself was posted on Southampton's official Twitter feed, in which he thanked the club for his time with them.
"I would like to take this opportunity to thank everyone for making my time at the club so special," he wrote.
"There have been ups and downs, but since the day I arrived I have given my all to play my part in pushing this club forward.
"It has been an honour to captain the club and lead the team out in a cup final at Wembley, achieve four successive top eight finishes and be part of the club playing back in Europe.
"The last couple of years have been more challenging but I believe the management and quality within the dressing room can bring success back."
Davis could make his second Gers debut in their Scottish Cup tie at Cowdenbeath on January 18, once the season resumes after the winter break.
