European treble winners in men's football history

In football, a team wins a treble when they win three major trophies in a single season. Winning the continental treble means winning the premier national league competition, main national cup competition, and main continental trophy, for UEFA which is the UEFA Champions League or UEFA Europa League. Though winning the Europa League is also considered a treble, it is not accepted wholeheartedly by the pundits and fans as winning the UEFA Champions League. Till now, 8 European clubs have been able to win the continental treble. Before we discuss all the European treble winners in men's football history, we must know about the types of Trebles we have in football. 

Continental treble

This is considered the actual treble in football where a team go on to win the national league, national cup competition and the main continental trophy. Celtic Football Club in 1966-67 became the first team in football history to win a Continental treble. Till now 22 men's teams have won the Continental Treble, with 30 being the total number of times. In Europe, only 8 football teams have been able to accomplish the feat.

Domestic treble

Generally for most of the footballing nations, winning a domestic treble is not possible since they do not allow first-division teams to win any secondary cup or league. A domestic treble includes winning three national competitions, including the national league title, the national cup competition, and one secondary competition. Countries which were under British or French possessions once allow domestic trebles to happen. Celtic with 8 domestic trebles and Rangers with 7, are the most successful teams when it comes to winning domestic trebles.
