Barcelona coach Ronald Koeman paid tribute to his compatriot Frenkie de Jong after the midfielder spared the Catalans' blushes in Wednesday's Copa del Rey tie with Rayo.
The Blaugrana appeared close to an embarrassing exit when they fell behind to the Segunda Division side with less than 30 minutes left on the clock.
But they eventually hit back with an equaliser courtesy of Lionel Messi, before De Jong struck 10 minutes from the end to clinch a 2-1 victory and progress to the quarter-final stage.
