The 25-year-old looks set to stay with the Scottish Championship side for another three years.
Harry Forrester has told Rangers' official website that he is targeting helping Mark Warburton's men get back into the Champions League after agreeing a new deal that will keep him at Ibrox until 2019.
The attacking midfielder had initially joined the Light Blues earlier in the season on a six-month deal (via Daily Mail), however his excellent form since signing has clearly persuaded Warburton to put him in his long-term plans.
The 25-year-old has scored five goals for the Gers - including one inside the first 13 seconds of the club's Scottish Cup tie with Dundee last month - to help the side book their place in the top flight for next year by clinching the Scottish Championship title while also helping them win the Challenge Cup and reach the Scottish Cup semi-final.
But while some may have been content with securing two medals - possibly with a third to come - and earning an extended contract during their first few months at a new club, Forrester is already targeting helping Rangers re-establish themselves on the continental stage.
"I want to kick on, I want to come back next year fit and ready to go and we want to get back in the Champions League at the end of next year so we need to get up there in the league and hopefully we can do that," he told the club's official website.
To reach the Champions League for the first time since the 2011-12 season, the Gers would have to end Celtic's dominance of the Scottish game by winning the league title.
But given how impressive they have been since Warburton arrived at the club, it appears that they stand a chance of at least challenging the Hoops next season, and perhaps sending them a warning for the future.
