5 English clubs you probably didn't know were once top-flight league champions

#2 Burnley

Burnley FC of Lancashire

Burnley's 30-game unbeaten streak in 1920-21 ensured that they won their first title in English football. The streak was the record for most games unbeaten in a season, before Arsenal managed their invincible season in the 20th century.

Burnley's recent good form aside, there has been little to cheer about for the Clarets in the more recent past, with a few promotion campaigns being the height of their achievements.

But the endurance of that 30-game unbeaten run from 1920-21 shows what an amazing side Burnley had with the record lasting an upwards of eighty years! That alone deserves a lot of recognition.

Burnley had some consistently high finishes in the periods between 1910-1923 with their side putting out some entertaining performances, but World War I probably robbed them of a consolidation process after winning their first FA Cup in 1914 and halting the flow of the side.

A forty year shallow period after the title success followed as the club were relegated in 1930 and in 1947 won promotion back to the top flight after the end of World War II. A youth-based team building policy with a progressive attitude resulted in Burnley winning their second league title in 1959-60.

Their manager Harry Potts was given a great deal of freedom to operate and this was the first time in history that a club gave absolute control over transfers and scouting to a manager.

Potts guided them to a European Cup quarter-final in 1961-62 and took Burnley into the Inter-Cities Fairs Cup (UEFA Cup/Europa League) in 1967 and had a long stint at the club.

Despite earning rave reviews for the way the club was run and their more-than-commendable consistent cup-runs, Burnley failed to win a trophy until they were relegated in the 1970s and they have never quite been the same club since.

Their recent Premier League form, therefore, is a deserved reawakening for the long-suffering Clarets supporters.
