The row between Dave King and the Rangers board intensified on Sunday night after he issued another statement questioning its integrity.

The former Ibrox director urged Light Blues fans not to buy season tickets and on Friday accused the board of an "extreme act of bad faith."

The South Africa-based Glaswegian was upset that the club have asked fans to renew their season tickets before the completion of a 120-day review of the business's operations.

Rangers, who have referred the matter to legal advisers, noted King's initial statement "with astonishment" and said he had made "a number of untrue allegations," but have not responded to his latest comments.

Manager Ally McCoist said: "If you don't believe and don't have faith in the club moving forward then you are in the wrong job and I have to be confident in that.

"I just look at the atmosphere our supporters created on Saturday and that tells me we have a chance.

"Our job is to go on to the park and win games of football and thankfully, more often than not, we have been doing that.

"And as I say, when you look at the atmosphere that we created inside the stadium on Saturday, that's why we need to keep believing.

"It is a hard enough job to do and if you let outside factors affect you then it is exceedingly difficult.

"So we have to batten down the hatches and concentrate on the football, which we did on Saturday."

Meanwhile, the Ibrox club announced a new three-year shirt sponsorship deal with online casino company 32Red, which starts from July.

Rangers chief executive Graham Wallace said: "We are in the process of rebuilding Rangers Football Club, and alliances with blue chip companies such as 32Red will assist us on our journey back to the top of Scottish football."
