Daniel Taylor for The Guardian:
They came in pursuit of what Gerard Piqué called “perfection” and, once again, they left the distinct sense this is the team that takes football to its highest levels. Lionel Messi and his exquisitely gifted team-mates put on a masterclass at times. They did not seem to care they were facing reputedly the best defence in the competition and it was a thrilling way to complete the treble of La Liga, Copa del Rey and now the trophy that means more to this institution than anything else.
Barcelona were outstanding. For neutrals this was a thoroughly enjoyable game but for supporters of other clubs it must seem daunting to ponder how on earth their team can compete with this squad.
