Foreign legions and perennial losers

Arsenal weren't the first side to field a non-English starting 11 - that distinction fell to Chelsea in 1999 and it was something that even Manchester United have done - but they are unique in choosing an entire squad without English, Scottish, Welsh or Northern Irish players.
By my reckoning, the most cosmopolitan squad now is not Arsenal's, but West Bromwich Albion's. If we exclude youth-team players who are yet to debut for the senior side, Albion can still count 20 different nationalities who have appeared for the first team this season: English (several players), Swedish (Jonas Olsson), Slovakian (Marek Cech), Cameroonian (Somen Tchoyi), Spanish (Pablo Ibanez), Scottish (James Morrison & Graham Dorrans), Czech (Roman Bednar), Northern Irish (Chris Brunt), Irish (Steven Reid), Welsh (Boaz Myhill), Congolese (Youssuf Mulumbu), Dutch (Gianni Zuiverloon), Ivorian (Abdoulaye Meite), Nigerian (Peter Odemwingie), French (Marc-Antoine Fortune), Romanian (Gabriel Tamas), Austrian (Paul Scharner), Chilean (Gonzalo Jara), Mexican (Carlos Vela, albeit on loan from Arsenal) and a New Zealander (Chris Wood). To further complicate matters, former manager Roberto di Matteo was born in Switzerland and played for Italy and current head coach Roy Hodgson has managed the national teams of Switzerland, the United Arab Emirates and Finland. Albion, incidentally, played in January's game against Blackburn where 22 different nationalities were involved, though not all at the same time.
