Former UEFA Cup and European Cup Winners' Cup winners Real Zaragoza will provide the opposition for this summer's annual prestige pre-season showpiece match.
The La Liga side will visit the Boleyn Ground at 3pm on Saturday 30 July, evoking memories of West Ham United's dramatic victory over the Aragonese in the 1964/65 European Cup Winners' Cup semi-finals.
The six-times Spanish Cup winners enjoyed an encouraging 2010/11 campaign, finishing 13th in just their second season back in the top flight, and are historically the ninth most successful Spanish club of all-time.
Managed by former Mexico midfielder and manager Javier Aguirre, Zaragoza possess an experienced squad that includes Uruguay defender Carlos Diogo, Argentina midfielder Leonardo Ponzio and Nigeria forward Ikechukwu Uche.
English football fans, meanwhile, will recognise Czech Republic midfielder Jiri Jarosik from spells at Chelsea and Birmingham City, and Paraguay centre-back Paulo de Silva from an 18-month stay at Sunderland.
The visit of Zaragoza will mark the fourth time the two clubs have met and the first since West Ham travelled to La Romareda for a pre-season friendly in 1973 which ended in a 4-1 defeat for the Hammers.
It was the aforementioned European Cup Winners' Cup semi-final that will conjure fonder memories for West Ham supporters, though.
Taking on a potent Zaragoza attack nicknamed 'Los Cinquos Magnificos' - 'The Magnificent Five' - West Ham raced into a two-goal lead in the first leg at the Boleyn Ground through goals from Brian Dear and Johnny Byrne. Zaragoza hit back, meaning the Hammers had a slender 2-1 lead to take to Spain.
The second leg started badly as Zaragoza went ahead on the night and ahead in the tie on away goals, only for Johnny Sissons to score an all-important equaliser and send West Ham through to the final, 3-2 on aggregate. At Wembley, of course, West Ham defeated TSV 1860 Munich 2-0 to lift the trophy.
Ticket news for what promises to be an exciting and colourful afternoon at the Boleyn Ground will be announced soon via whufc.com and the club's official twitter feed here.
