The East Londoners will face Andorran runners-up Lusitans in the First Qualifying Round of the Europa League, with the first match as early as next week.
1.) Lusitans are a very young team - not in the sense that their squad are made up of young players but because they were only founded 16 years ago in 1999. They come from the capital city of Andorra la Vella, a city of just 22,000 inhabitants. The entire city could squeeze inside Wembley four times over.
2.) The club won promotion to the Andorran top flight in its first season, though they didn't need a particularly lengthy ascent up the leagues as there are just two divisions in Andorra. Still, they went up to the Primera Divisio as second division champions, which isn't bad in your club's first campaign.
3.) Lusitans have close ties with Portugal and Portuguese culture. The club were mostly founded from Andorra's Portuguese community, and are mainly made up of Portuguese nationals alongside Andorran and Spanish players. They utilise Portugal's colours of red and green, as well as the national side's emblem.
4.) Since being promoted in 2000, Lusitans have won the Primera Divisio twice, both of which came in successive years from 2011-13. Their Champions League qualifiers didn't go so well though - they lost 9-0 to Maltese side Valletta FC one year and 7-3 to Icelandic outfit EB/Streymur the next.
5.) West Ham are by far the highest profile team they have faced, and the Hammers will be coming up against one current Andorran international in Oscar Sonejee, a midfielder with 100 caps who had a little bit of handbags with Wayne Rooney when England went to the country in 2007.
