Of the 699 players who appeared for Championship clubs during the 2011/2012 season 387 were English. As you’d expect the other nations from the British Isles also featured heavily with (and no, this isn’t a joke) 52 Scotsmen, 50 Irishmen, 28 Welshmen and 19 Northern Irishmen.
The table below shows data on each of the twenty-four clubs in the Championship and the nationalities who played during the 2011/2012 season. The columns are as follows, Nats: number of nationalities used, Plyrs: total number of players used, Eng: Englishmen used (Sco, Wal, NI, Ire self-explanatory). %Eng is the percentage of the total number of players used who are English whilst %B&I is the percentage of players used who are from England, Wales, Scotland, Northern Ireland or the Republic of Ireland. Whilst I understand that Ireland is a foreign country I feel that this metric is useful as players from the Republic of Ireland have been integral parts of squads in the football pyramid for many years.

Championship nationalities 2011/2012
Relegated Portsmouth are the side that can most adequately be labelled as the division’s “foreign-legion”, though it has to be said that the term “foreign legion” exited the football lexicon a few years ago. I think it dropped out of common usage at the same time that the goalkeepers union was finally disbanded.
Doncaster Rovers’ (Willie McKay inspired) policy of recruiting anything that moved during the second half of last season leaves them having used the most players in the division (41). Play-off semi finalists Birmingham City used the fewest players having only used 22 during the season. It’s a real credit to the Blues as they also had a gruelling (and very fun) sojourn in the Europa League to navigate.
Peterborough United fielded the highest percentage of English players (79%) but it was Barnsley who used the most (28). In fact the only player that Barnsley used who originated outside of the British Isles was Ricardo Vaz Te, and he signed for West Ham during the January transfer window.
Blackpool used the most Scottish players (7), Crystal Palace used the most Welshmen (4), Burnley were the club who fielded the most Northern Irish players (5) whilst Palace and Ipswich Town fielded the most Irishmen (5).
