Ousmane Dembele and Martin Braithwaite scored in extra time to see Barcelona past a resilient Cornella 2-0 in the Copa del Rey on Thursday.

Ronald Koeman's men had two penalties saved in normal time as they failed to break down the Segunda B side who famously knocked out Atletico Madrid in the previous round.

Miralem Pjanic and Dembele each missed from the spot but the latter eventually made the breakthrough with a powerful strike.

The visitors made sure of the win in the very last moment through Braithwaite to ensure there would be no repeat of Wednesday's action, when Real Madrid suffered one of the biggest shocks in the competition's history by losing to Alcoyano.

Barca struggled to turn possession into chances, their first real effort of note coming via a Francisco Trincao volley from Pjanic's corner that was parried by Ramon Juan.

Pjanic had the chance to break the deadlock from the spot after Ronald Araujo took a high foot to the head, but his penalty was expertly saved.

They started the second half with more purpose and should have scored when Martin Braithwaite shot straight at Ramon after Antoine Griezmann diverted the ball into his path.

Griezmann then blasted over the bar with the goal at his mercy after a clever quick free-kick from Pjanic, and Neto had to make a flying save to parry an Agus Medina strike barely a minute later.

Substitute Dembele was given the chance to get the breakthrough 11 minutes from time after another high boot in the box, this time from Pol Moreno on Clement Lenglet, but Ramon held his nerve and blocked the penalty from the middle of his goal.

Braithwaite sliced another clear chance wide of the right-hand post and Ramon came to the rescue again to tip a Pjanic half-volley onto the crossbar and away.

Yet within two minutes of the beginning of extra time, Ramon's resistance was broken, the keeper getting two hands to Dembele's strike from 20 yards out but unable to keep the ball out of the net.

Konrad de la Fuente almost made it 2-0 immediately after coming off the bench, but Ramon threw himself to his left to make another fine stop, before Albert Estelles earned a second booking in the closing moments for a poor challenge on the excellent Araujo.

With the final move of the game, Dembele combined expertly with Pedri, who unselfishly teed up Braithwaite to drill into the unguarded net.

What does it mean? Barca avoid more disappointment – just

This was the first time in their history that Barca had three consecutive games go to extra time, having twice gone the distance in the Supercopa de Espana.

After losing the final to Athletic Bilbao, it was important for Koeman's changed side to respond here and he will be relieved that they eventually found a way through.

With the two Madrid giants already out, the Copa del Rey looks like Barca's safest bet for silverware this season.

Ramon-believable

Ramon made seven excellent saves, including the two penalties, and he will be furious he could only parry Dembele's shot into the top-left corner.

Still, were it not for their keeper, Cornella could well have suffered a straightforward defeat in normal time. 

Puig poor

Riqui Puig has found it difficult to convince Koeman at times and this was not a performance to earn the trust of his coach.

The midfielder, booked for dissent seven minutes in, managed no shots, crosses or key passes and was taken off at half-time.

What's next?

Barca are back in LaLiga action away to Elche on Sunday.

Barcelona coach Ronald Koeman believes Lionel Messi is slowly getting back to his best after a brace against Athletic Bilbao.

Messi scored twice, to go with Pedri's goal, at San Mames on Wednesday as Barca recorded a 3-2 victory.

The star has been involved in 10 goals in his past 10 games in all competitions, netting eight and assisting two.

And Koeman feels Messi, who has netted 12 times in 20 appearances this season, is improving.

"Since the first day that I arrived at the club I think Lionel Messi has given everything," he told a news conference.

"I haven’t been surprised by his quality because he's obviously been showing how good he is for years. It's possibly true that he's been less effective than normal which is why there could have been doubts but he's doing a lot better now, he feels comfortable at the moment and he feels up for the challenge.

"That's how I feel. But I think Messi is the one who can answer that best."

Pedri cancelled out Inaki Williams' opener before Messi's double, and Barca moved into third in LaLiga despite Iker Muniain's late goal.

Koeman also praised Ousmane Dembele, who along with Pedri and Antoine Griezmann had a game-high three key passes.

"I think everything starts with the player himself. If the player feels comfortable and feels physically fit he can play well," he said.

"I don't think there's ever been any question about his quality, at least in my opinion, but there have been doubts about his ability to stay fit. At the moment he seems fully fit and I have to think about the programme of games ahead and when we can give him a rest because he hasn't played regularly for quite some time.

"He has to learn how to manage his game time as well. But in terms of the football he can play we know what he can give to the team. He's very good going forward, he attacks with the ball and those are good qualities for us."

Barca, who are seven points behind league leaders Atletico Madrid and have played two more games, visit Granada on Saturday.

Barcelona moved into LaLiga's top five after Frenkie de Jong's goal clinched a 1-0 victory over bottom club Huesca in Lionel Messi's 500th league appearance for the club.

Blaugrana boss Ronald Koeman, who warned before the game that defeat would all but end his side's title challenge, saw a much-improved Barcelona performance as he earned back-to-back LaLiga away wins for the first time in his tenure.

Messi came back into the side after missing Barca's disappointing 1-1 draw with Eibar due to an ankle injury and was at his talismanic best, deftly assisting De Jong's volleyed goal after just before the half-hour mark.

Huesca did open the visitors up on occasion and it remains to be seen whether Koeman can restore some consistency and style to this team, but they did enough here to climb above Sevilla in the table.

Barcelona's early pressure paid off after 27 minutes when Messi played an exquisite chipped pass into the box, where De Jong evaded two defenders and guided the ball into the corner of the net from six yards on the volley.

Messi would have capped a fine first-half performance with a superb goal five minutes from the interval had Alvaro Fernandez not pulled off a spectacular save, palming his dipping 20-yard free-kick over the crossbar.

The six-time Ballon d'Or winner flashed a fierce effort narrowly wide from the edge of the box early in the second period, before Marc-Andre ter Stegen got down well to prevent Rafa Mir's close-range shot from becoming the equaliser.

Ousmane Dembele should have put the game beyond doubt when he went one-on-one with Fernandez 13 minutes from time, but the Huesca goalkeeper saved at his feet and then denied Messi again before full-time.
