	Having left GAIS at the end of his contract, Çelik was offered a three and a half-year contract from Scottish Premier League team Rangers, which he signed on 20 January 2012. After Rangers went into administration, Çelik chose to leave the club in March 2012 without a pay-off. He stated that he didn't make the wrong decision in joining the club, but the club entering administration was unpredictable.
