Willie Henderson has told Rangers' official website that Mark Warburton's confidence in Joey Barton is what is convincing him that the midfielder will turn out to be an excellent addition to the Gers' squad.
The 33-year-old recently agreed a deal to become part of the Light Blues side ahead of their return to the Scottish Premiership.
And Ibrox hero Henderson stated that as well as assessing the move based on his own opinion of the player, the manager's track record gives him plenty of belief that Barton will prove to be a great signing.
"He seems to be a very good player who has had a very good career down in England. I am a great believer in Mark Warburton – he has done an excellent job since he has come up here, and if Mark thinks he is a player who is going to benefit Rangers Football Club, I'll go along with that," he told the club's official website.
While Rangers have strolled to the Scottish Championship title this past campaign, their recent form meant that the season ended on a slight sour note, especially as it saw them lose the Scottish Cup final.
Barton's experience at the highest level would have surely prevented that kind of run happening as he would have made sure that every player was concentrating on giving everything until the curtain had come down on the season.
There is no doubt that many of the club's current squad have the potential to play for a team battling for the title in the top flight, and in Europe also, but they arguably need Barton to help them eliminate the naivety that cost them more success in the final weeks of the season.
