#5 Roma 3-0 Barcelona (2018)
It isn’t often that a team as good as Barcelona blows a two-goal lead over two legs of a Champions League tie. The Spanish giants won the first leg 4-1, which should have given them an unassailable lead, with two own goals helping them take control of the tie.
Roma gave themselves a slim ray of hope in the early minutes of the second leg, with Edin Dzeko giving them the lead. Daniele de Rossi’s penalty just after the break reduced the deficit to one, before Kostas Manolas popped up with a header in injury time to give Roma a historic win. They went on to reach the semi-finals, where they were beaten 7-6 on aggregate by Liverpool.
