Koeman delighted by Barcelona's 'incredible' Copa del Rey win over Sevilla

Barcelona were clearly not affected by off-field events as they produced a rousing fightback to reach the Copa del Rey final.

Ronald Koeman was full of admiration for the mentality of his Barcelona players after they produced an "incredible" comeback to advance to the Copa del Rey final with a 3-0 win over Sevilla.

Barca started a dramatic second leg at Camp Nou on Wednesday with a two-goal deficit, but won the tie 3-2 on aggregate to set up a final against Athletic Bilbao or Levante.

The Catalan giants hit the headlines at the start of the week when ex-president Josep Maria Bartomeu was among those arrested on Monday – he was then provisionally released under charges of unfair administration and corruption of business – as part of a police investigation into last year's 'Barçagate' scandal.

There was no sign of any turmoil as Ousmane Dembele put Barça in front early on and Gerard Pique made it 2-2 with a last-gasp header to force extra time midweek.

Lucas Ocampos had missed a chance to level on the night when his penalty was saved by Barça goalkeeper Marc-Andre ter Stegen with 17 minutes remaining and Sevilla had Fernando sent off before Pique struck.

Martin Braithwaite put Barça in front early in extra time and Luuk de Jong – who had been substituted – was shown a red card on the touchline for dissent after Sevilla were denied another penalty.

Barça head coach Koeman hailed the character shown by his side, who also beat Sevilla 2-0 in LaLiga on Saturday.

The former Netherlands boss said after the match "We always believed. We never gave up on the Copa. It's a question of mentality.

"I, as a coach, can't ask my team to do more than what I've seen tonight. We fought until extra time and it's incredible. I'm very happy with the team's work tonight.

"We deserved to go through. I think we were better over the two legs. We were the best team."

Koeman added in a week that will end with the Barca presidential election: "We managed to score three goals and could've scored more. You can't ask for more."
