FC Barcelona head coach Ernesto Valverde took full responsibility for their shock defeat to AS Roma in the UEFA Champions League which marked their third consecutive European quarter-final exit.
Current mood in Barcelona.
"I know the guys can play - look at how we played against Chelsea and stuff like that - we know we can put it together, you just have to execute it for 90 minutes".
Jurgen Klopp has beaten Pep Guardiola more times than any other manager, with Tuesday's 2-1 second-leg win taking the tally to seven victories from 13 meetings.
"It was something nearly impossible", Roma midfielder Radja Nainggolan said, "but in the end it became possible".
Then near the hour mark, Dzeko earned a penalty that Daniele De Rossi converted to set the stage for Manolas' late header.
Dzeko also waxed lyrical about his side's tactics and said he played with more freedom alongside Patrik Schick in attack, with Radja Nainggolan, who missed the first leg with injury, behind them.
Roma have brought some pride back not just to Rome, but to Italian football after the country's humiliating failure to qualify for the World Cup earlier in the season.

Sir Alex mingled with Roma's victorious players after the match and congratulated Rome's most famous son, Francesco Totti, on the result.
