The former Newcastle United and Queens Park Rangers midfielder has joined the Scottish Premiership-bound side on a free transfer.
The Glasgow giants recently signed former QPR defender Clint Hill on a free as well.
Barton is pleased with the way the current Rangers squad is staking shape, and has made an interesting observation.
“You need a mixture,” Barton told Rangers’ official website. “Last year Rangers had that with Kenny Miller and Lee Wallace and a few boys who know the club inside out and have a bit of experience.
“Going on to the challenge of next season it’s always good to have that in the building.
“You don’t want to have too much of one or the other, it’s about getting a nice balance, a nice mixture.
“It clearly seems like it’s something that the gaffer and the coaching staff have been aware of heading in to the recruitment this summer, so I think it puts us in great stead.”
Rangers already had some very good players in their squad, such as Barrie McKay, Wes Foderingham and Martyn Waghorn, and adding the likes of Barton, Hill and Jordan Rossiter is only going to make them better.
The Gers won the Scottish Championship title with ease last season, but they will find the Scottish Premiership much more difficult and more competitive.
Mark Warburton’s side will start the 2016-17 campaign aiming to win the league title, but Old Firm rivals Celtic will be favourites.
Finishing second or third should not be considered a failure for Rangers, who should be looking to use the 2016-17 campaign to consolidate their place in the Scottish top flight.
