The off-field players are fast becoming as well-known to fans as those who who appear on the pitch. Here's how they line up: 

Craig Mather: The current chief executive invested £1 million after Charles Green's consortium bought the club, and has worked hard to gain the trust of manager Ally McCoist and chairman Walter Smith.

Charles Green: The businessman, who was previously chief executive of Sheffield United, led the consortium which bought Rangers after administration and liquidation last year. He stepped down as Ibrox chief executive in April this year amid claims he was linked to disgraced former owner Craig Whyte but is now back with the club in a consultancy role.

Brian Stockbridge: The Rangers finance director was drafted in under Green and is understood to be close to former director Imran Ahmad.

Imran Ahmad: The power behind the throne. Recruited Green to front the consortium, but axed from the club as commercial director earlier this year

Bryan Smart: Businessman Smart, who is a former boss of Mercedes-Benz UK, was appointed a Rangers non-executive independent director in December. He is understood to be an ally of Ahmad.

The other camp

Jim McColl: McColl owns engineering group Clyde Blowers which has an estimated turnover of £1.35 billion. His personal wealth has been put at £1bn and he was number five in the Sunday Times Scotland Rich List.

Paul Murray: Former director was appointed to the Rangers board in September 2007 and resigned in May 2011 when Craig Whyte assumed control. He led a failed bid to take over the club last year.

Frank Blin: Blin is the retired boss of accountancy firm PricewaterhouseCoopers Scotland. The group of shareholders including McColl want to appoint him to the board to forensically examine the club's finances.

Walter Smith: Former Rangers manager, Smith became non-executive chairman of the club in May this year. He led a consortium that tried to buy the club from Green last summer but withdrew the bid. Smith is likely to back McColl's bid.
