Editing Double (association football) (section)

===European double===
In the same spirit as the European treble, the European double consists of winning the top tier European tournament (currently the [[UEFA Champions League]]) and domestic league title in a single season or calendar year. This has been achieved on 31 occasions by 16 clubs from 56 European competitions. [[FC Barcelona|Barcelona]] and [[Real Madrid CF|Real Madrid]] has achieved this on the most occasions (5). [[AFC Ajax|Ajax]] and Real Madrid are the only teams that have successfully defended a European double. [[José Mourinho]] has the unique distinction of being one of two manager to achieve this double with two different clubs, having done so with [[FC Porto|Porto]] (2004) and [[Inter Milan]] (2010). Likewise, career rival [[Pep Guardiola]] achieved the same feat with [[FC Barcelona|Barcelona]] (2009) and [[Manchester City F.C.|Manchester City]] (2023). Additionally, both of Guardiola's doubles are also [[Treble (association football)|trebles]] as Barcelona won the Copa del Rey and City won the FA Cup in their respective seasons in addition to the two trophies.
