Chairman Tony Bloom has led the tributes to Sue Addis, who has died at the age of 69.
Sue had run the popular Donatello restaurant in the city with her partner Pietro since 1987 and they became big supporters of the club, sponsoring the club’s shirts and hosting parties and get-togethers for players and staff for many years.
She was also a keen supporter of charities in the city, helping to raise thousands of pounds for homeless charities and other good causes.
Tony said, “Everyone at the club was devastated to learn the news. Sue had always been a great supporter of the Albion, and Donatello's is woven into the fabric of the club - both literally and metaphorically.
“As shirt sponsor, they supported the club in some of its toughest times and have remained as a loyal backer ever since, sponsoring the family stand and the dugout in recent seasons.
“And even more than that it is the warm and genuine welcome that players, staff and fans have always been afforded in the restaurants over the years. Be it our annual pre-season meal for the directors, staff and players, Christmas dinners or many of the charity fundraisers we've held at Donatello, Sue and her boys have always been fabulous hosts.
"We held our celebrations there when we were given permission to build the stadium and they opened the doors to film with US TV network NBC on our promotion to the Premier League, supplying hungry crew with endless pasta and pizza.
“Sue was a great supporter of the club, by our side or on our shirt through the good and bad times, and our deepest condolences go out to Sue’s family, in particular Pietro, sons Leo, Stefano and Mikele and her many friends.”
