The former Gers midfielder believes the 33-year-old can be just what the club will need next season.
Recent days have seen the Glasgow side linked with a move for the 33-year-old former England international as they look to significantly bolster their side ahead of their return to top-flight Scottish football.
Barton joined the Clarets on a one-year deal from Queens Park Rangers last summer and enjoyed a stellar season, being named the club's player of the year as they won the Championship and also being named in the league's team of the year.
A free agent at the end of June, the former Manchester City and Newcastle United man is considering his options and there is widely thought to be concrete interest from Mark Warburton's side.
De Boer, who scored 40 goals in 129 games for Rangers across four years at Ibrox, believes that Barton can be a crucial leader in midfield as the club contend with their return to the Premiership and potential Europa League football next season.
The Dutchman said, as quoted by BBC Sport: "He has knowledge of the game, he's seen everything; it's important because the team is young.
"They need a guy with experience, on the pitch and at the training ground. You need a leader; Barton can do that."
Barton would certainly bring a wealth of wide-ranging experience to a relatively young Gers side, having played in the Premier League, the Championship, and France's Ligue 1.
In his often controversial career, the midfielder has been relegated and then immediately promoted back again with Newcastle, spent a year with Marseille, won promotion with QPR, and now enjoyed a third Championship promotion with the Clarets.
