League and League Cup Double
A rarer ( though less coveted ) domestic double is that of winning the league championship and the League Cup . In many leagues , this can not be done as there is no second domestic cup competition ( such as in Italy and the Netherlands ) or it has been disbanded ( such as in Spain and Denmark ) . The format of league cups and the number of participating teams can vary enormously from one country to another . In the case of Germany , the DFB-Ligapokal was played in the summer months prior to the Bundesliga and therefore was won in the preceding calendar year to the title win .
The Double, in association football, is the achievement of winning a country's top tier division and its primary cup competition in the same season. The lists in this article examine this definition of a double, while derivative sections examine much less frequent, continental instances. The Double can also mean beating a team both home and away in the same league season, a feat often noted as doing the double over a particular opponent. The first club to achieve a double was Preston North End in 1889, winning the FA Cup and The Football League in the inaugural season of the league. The team that holds the record for the most doubles is Linfield of Northern Ireland, with a total of 24.
