Died in January, completely missed by me (and seemingly the forum?) but worthy of a mention. Nils Arne Eggen, aged 80. He was the football manager who absolutely dominated the Norwegian league with Rosenborg in the 90s and turn of this century, turning the Norwegian side into a hard nut to crack in Europe who famously beat English champs Blackburn Rovers, and also got to the Champions League quarterfinals once (!). When he retired, he said Rosenborg would go onto become a giant of the European game, which is not one of the more successful predictions there's been.
Also he used to call defensive football "arse football" which is still a common quotation in Europe.
The Sun produced an obit unnoticed at the time.
