Danish brewing group, Carlsberg, is expected to be among the five or six largest sponsors of the 2004 European soccer championships, which are to be played in Portugal. The group is due to make an announcement on Friday at a press conference which will be attended by Carlsberg's chief executive, Nils S. Andersen, Lennart Johansson, UEFA president, and Dr. Gilberto Madail, chairman of Portugal's soccer federation. Carlsberg was a principal sponsor of the two preceding European Soccer Championship finals in 1996 and 2000.
