Fc Barcelona has been winning either Copa del Rey or the double (CdR + La Liga) past 3 years. 2017/18 La Liga winners has failed to win the Champions League 3 times in a row. Last time the club won the Champions League, was in 2015. The year when Catalan club became the first club to win the treble for the second time. First time Barcelona won treble was in 2008/09 during the Guardiola era.
So what has made the Champions League harder for Barcelona ?
Firstly it’s their eternal rivals Real Madrid, who in fact, have been crowned the champions those past 3 years. This year Real is starting without their main star Cristiano Ronaldo and Zinedine Zidane, under whom the Madrid club made history by winning CL 3 times in a row. Real lost 4-2 to Atletico Madrid in the Supercup but had a promising beginning in La Liga by beating 2-0 Getafe.
Secondly it’s the tactical changes that Luis Enrique kept using and Ernesto Valverde is repeating the same mistakes.
It was Enrique’s first year at the club, when they made history just like Pep Guardiola. But Valverde couldn’t have the same result as those two.
Barcelona has won the champions league 5 times in the club’s history. And as mentioned, since 2015 the club seems to be cursed.
