After losing against Bayern in the Cup, only two teams can win it all
Treble: one of the forbidden words at Camp Nou. Winning it all. The league, the Cup and the Champions League. Only two teams can do it in Europe: Juventus and Barcelona.
Pep Guardiola's Bayern Munich was also in the run for the three titles but they lost to Borussia Dortmund on Tuesday in the German Cup semfinal.
The Europa League semifinalists (DniPro, Sevilla, Fiorentina and Napoli) can't win their leagues, which means also Juventus (Masimo Allegri) and Barcelona (Luis Enrique) can win the treble.
Leaders in the league, finalists of the Cup and in the CL semifinals against Bayern Munich. With the level of Messi, Neymar and Suarez currently, anything is possible.
Juventus are Italian league leaders, in the Cup final and Champions League semifinalists. In fact, they have almost won the league, with 14 points more than Lazio. On June 7th they play the Cup final against Lazio.
