The League representative team wins the FA Carlsberg National League System Cup at the first attempt by beating the Midland Combination (Division 1) on penalties at Coventry City F.C.'s Ricoh Arena in May 2008.

The team remains undefeated and does not concede a goal but finishes runners-up to the Republic of Ireland team thus missing out on qualifying for the final tournament.

The League is nominated by the AFA to take part in an FA Charter Standard League pilot scheme having been identified as having one of the highest proportions of FA Charter Standard member clubs in the country.
