Celtic and Rangers today unveiled a three-year joint sponsorship deal with lager brand Carling worth up to £12 million.
The "Old Firm" will wear the drinks firms logo on their shirts from next season when their current deal, a joint initiative with troubled communications firm ntl, runs out.
Carling, which is owned by the American Coors company, had previously sponsored the English Premiership and had separate deals with a number of clubs there.
