Scott Nisbet has advised current boss Mark Warburton to keep four key members of the set-up at Ibrox this summer.

The former Rangers defender has claimed  players Kenny Miller, Lee Wallace, Andy Halliday and assistant manager David Weir are all crucial to the Old Firm club’s chances in the Premiership next season.

In an interview with the Glasgow Evening Times, Nisbet made it quite clear why a total squad overhaul won’t bring success.

“Kenny Miller knows what Rangers is about, Lee Wallace knows what Rangers is about, Andy Halliday knows what Rangers is about and Davie Weir knows what Rangers is about,” Nisbet said.

“It is massive to keep that connection at Rangers. You can bring in players, but you need to keep that Scottish identity.”

Four players have already been recruited this summer as Warburton builds a squad capable of competing in the Scottish Premiership.

Notably, Jordan Rossiter has been brought in from Liverpool while the vastly experienced Joey Barton has arrived from Burnley and been tipped as a crucial signing.

Miller, 36, is currently enjoying his third stint with the Glasgow giants and this season helped the club to promotion with 14 goals in 32 league games.

Wallace has played in Scotland his whole career and the 28-year-old has cemented himself as first choice left-back since signing from Hearts in 2011.

Defensive midfielder Halliday has only been at the club for one year since leaving Bradford City, but was rock solid as the club were promoted and the Glaswegian 24-year-old could form a crucial partnership with Barton in central midfield.

More transfers are expected at Ibrox over the coming months, and on Tuesday Football Insider reported Warburton wants to make Matthew Stevens his fifth signing.

In other Rangers news, they have released their squad for the summer tour and there is one summer signing omitted.
