In normal time, Barcelona missed two penalties, with midfielder Miralem Pjanic thwarted by Cornella keeper Ramon Juan late in the first half before Dembele struck straight from another spot-kick at the feet of the 21-year-old in the 80th minute.
Ousmane Dembele and Martin Braithwaite’s extra-time strikes helped Barcelona to edge past stubborn third division neighbors Cornella 2-0 and reach the last 16 of the Copa del Rey on Thursday. Barcelona missed two penalties in normal time, with Cornella keeper Ramon Juan thwarting midfielder Miralem Pjanic late in the first half before Dembele struck straight at the feet of the 21-year-old in the 80th minute from yet another spot-kick.
In the second minute of extra-time, Dembele made amends with a vicious long-range shot that Ramon Juan got a hand to but was unable to keep it from rocketing into the net.
Braithwaite, a Danish forward who had missed a straightforward opportunity to win the game late in regular time, then sealed a nervous Barca victory moments after Albert Estelles’ Cornella was sent off.
Barca is the only remaining team of Spain’s top three clubs in the last-16 Friday draw after Alcoyano knocked out Real Madrid on Wednesday, though Atletico Madrid’s La Liga leaders were beaten by Cornella last week.
Barca coach Ronald Koeman was happy to reach the next round but was disappointed with the failure of his side to kill the game off long before, meaning that after playing extra time in the Spanish Super Cup against Real Sociedad and Athletic Bilbao last week, they played 120 minutes for the third match in a row.
“The most important thing is that we got through to the next round but we cannot be happy because we missed a lot of clear chances, we missed two penalties and we need to show more responsibility in games like this,” he told reporters.
“We played 120 minutes once again, that’s a big thing for us. And after creating so many chances and missing two penalties. This cannot be.”
Cornella coach Guillermo Fernandez Romo said he was proud of his team, but also sad that they were unable to finish the job.
“I don’t feel good about the result but everything else I saw tonight makes me proud. We played with dignity and I’m so impressed with my players because my impression is that it was an even game until the 80th minute,” he said.
