Glasgow Rangers boss Mark Warburton has taken seven players to Ibrox this summer.
The veteran midfielder joined Rangers on a two-year deal last month after helping Burnley win promotion back to the Premier League last term.
The 33-year-old will bring plenty of experience with him to Ibrox, having played with Manchester City and Newcastle United in the past, and Holt admits that he can't wait to team up with the Gers new boy.
"It'll be great to play alongside a player like Joey Barton and I'm sure that he will be a great signing for the club," he told Rangers TV, via The Mail.
"I'm sure that he will have a really positive impact at the club, in at the training ground and on the field. I'm really looking forward to him joining and working with him"
Barton is one of seven signings made by Rangers boss Mark Warburton this summer.
He followed fellow Liverpudlian Jordan Rossiter to Glasgow, while Clint Hill, Niko Kranjcar and Matt Gilks were later signed by Warburton. Josh Windass and Matt Crooks also arrived after officially joining the club back in January.
Barton is yet to join up with his new team-mates for pre season but Rangers are in South Carolina at the moment for a 10-day training camp as their season kicks off next month.
