The Sweedish striker Henrick Larson played many years for Celtic in Scotland, but played only a year for Manchester United.

In 1967 Glasgow Celtic won the European Cup with a team of players who were all Scots born within a 30 miles radius of the clubs football ground Celtic Park. This team became known as the Lisbon lions. I am not sure this is a unique achievement within Europe but it is within the UK and Ireland.
