Celtic legend Paul Lambert has told beIN Sports that it was the wrong decision for Rangers to be demoted into the fourth tier of Scottish football back.
The Gers finished second in the Premiership in 2012 but the Ibrox side were booted into the third division after 25 out of 30 Scottish teams voted in favour of their demotion.
Rangers went into administration that previous February and it was revealed two months later that there were £134 million of unpaid debts.
During their absence, Celtic won five Premiership titles on the spin under Neil Lennon and later Ronny Deila, while the Hoops won a sixth straight crown and finished a massive 39 points ahead of their Old Firm rivals on their long-awaited return to the top flight last season.
Scottish football as a whole suffered on a financial level from the Gers' near-obliteration after BSkyB and ESPN pulled the plug on television deals worth around £80 million over five years.
And Lambert says that it was a terrible decision for those 25 clubs to send the Ibrox club to the basement of Scottish football.
He told beIN Sports: "I think it was the worst decision to demote Rangers three leagues. It wasn't good for the Scottish game, the Scottish league and certainly not for the national team.
"Celtic and Rangers, in years gone by, provided a lot of players for the national team and it's mainly Celtic now. That's the bigger picture and people hadn't really thought it through. Nobody thought, 'Well how is this going to affect Scotland, the league itself, Glasgow as a city'?
"I think it was the wrong decision to put them down three leagues."
