Barcelona's Lionel Messi looks dejected
Barcelona were eliminated from the Champions League this week by Juventus, beaten 3-0 on aggregate.
They had entered the tie at the Nou Camp 3-0 down after an Italian masterclass in Turin, and could not get their dream comeback going despite heroics against PSG in the previous round.
The quarter-final defeat prompts a moment of reflection for the Catalan club, but they have been through tougher losses.
Spanish journalist Albert Montagut wrote for newspaper Mundo Deportivo this week that he classes their 1975 defeat to Leeds United as their very worst in his memory, putting the Juventus elimination in perspective.
He wrote: "One of the best Barça of all times, the one led by Johan Cruyff , fell eliminated in the Camp Nou in the semifinals of the European Cup against Leeds United... it meant the end of the dream after Johan's arrival."
Montagut went onto add that he can still clearly recall Leeds fans wildly celebrating their 3-2 aggregate win while Barcelona fans trudged back to their homes at the final whistle.
He described this defeat to a Peter Lorimer inspired side as more heartbreaking than any of their recent losses, which include a 2010 semi-final loss to Jose Mourinho's Inter, being beaten by Roberto di Matteo's Chelsea and elimination at the hands of Atletico Madrid.
Leeds faced Bayern Munich in the final in 1975 in a controversial game in which Bayern won 2-0 but the Whites had a goal unfairly ruled out which would have changed the course of the match.
