Ronald Koeman insisted Barcelona remain upbeat and optimistic in their pursuit of the LaLiga title, despite suffering Clasico pain at the hands of Real Madrid.

Barca left the Spanish capital emptyhanded after Karim Benzema and Toni Kroos guided defending champions Madrid to a 2-1 win on Saturday.

Oscar Mingueza set up a dramatic final half-hour with his second goal of the season for Barca, while Madrid midfielder Casemiro was sent off in the 90th minute.

But Madrid held on at a sodden Alfredo Di Stefano Stadium to seal a third consecutive win against Barca in all competitions for the first time since 1978 as they provisionally moved top of the table, with Atletico Madrid in action on Sunday.

Barca are third and a point off the pace, though they could fall four points adrift if Atletico beat Real Betis.

"Of course we're still upbeat and optimistic because we've produced a serious performance," Barca head coach Koeman told reporters. "We are fighting.

"We lost a match against a team who are fighting to win the league but there are nine matches and all the matches are important for the three best teams.

"It's difficult for all three of us. We will come back, we will fight until the last match."

Barca attempted 12 shots in total in the second half, three of those on target, and nearly snatched a point when Ilaix Moriba struck the crossbar in the 94th minute.

But, Koeman became the first Barcelona coach to lose his first two LaLiga games against Madrid since Joaquim Rife in 1980 (also the first two).

Koeman could not hide his frustration post-match, having felt his side should have had a penalty when substitute Martin Braithwaite went down in the box under pressure from Ferland Mendy.

The former Netherlands boss said: "I'm not the only person who's upset about the decision, or lack of decision.

"The players feel disappointed because of this decision by the referee to not give the penalty and there's players who have been playing for years for Barcelona, so I know. But once again not all decisions were right.

"You should ask the players but I would like to include myself. We know that we've played a good match football wise, the first part, the first half, ok, we were not up to our standards. Real Madrid defended very well in the first half.

"There's no [league] match next week and the title [Copa del Rey final against Athletic Bilbao] is at stake. We have a week to prepare for a difficult match so we'll carry on and we are strong."

Lionel Messi, meanwhile, failed to score in seven consecutive Clasicos in all competitions for the first time in his career.

Ronald Koeman insisted Barcelona were denied a "clear penalty" in their 2-1 loss to Real Madrid as he hit out at the officiating in Saturday's dramatic El Clasico.

Barca fell to a third consecutive defeat to bitter rivals Madrid in all competitions for the first time since 1978 as they missed out on the chance to move top of LaLiga.

Oscar Mingueza set up a thrilling final half-hour at Estadio Alfredo Di Stefano when prodding in to halve the deficit following first-half strikes from Karim Benzema and Toni Kroos. 

The visitors attempted 12 shots in total in the second half, three of those on target, and nearly snatched a point when Ilaix Moriba struck the crossbar in the 94th minute.

However, Koeman felt his side should have had a penalty when fellow substitute Martin Braithwaite went down in the box under pressure from Ferland Mendy.

And the Dutchman also questioned why more time was not added on at the end as a portion of the four allotted minutes was taken up by the officials resolving a technical issue.
 
"If you're a Barca fan or a Barca player, you're very unhappy with the result because I think there were two clear decisions that the referee didn't make that would have changed the game," he told LaLiga TV.

"I think we weren't good at all in the first 45. We weren't good in attack and we weren't good in defence.

"In the second half we improved but I only ask for a bit better when making key decisions because they are decisions that could have cost us the game and eventually they did.

"I think the added time as well was four minutes and it should have been added on. 

"He only added two minutes because of the issue with his microphone and there were quite a few more stoppages, also with the possible penalty towards the end. Once again, we have to accept it and shut up."

Defeat for Barca was their first in 20 league games since early December and saw them drop to third in LaLiga, a point behind Real Madrid and Atletico Madrid, the latter of whom play their game in hand against Real Betis on Sunday.

When asked by reporter Ricardo Sierra if the two decisions that went against his side were defining moments, Koeman said: "Yes, of course. 

"The issue with the referee's microphone is a different issue completely. Obviously there were many things on the pitch that affected the result overall

"But I do think we should have gotten a clear penalty towards the end and I don't know why it wasn't reviewed by VAR.

"The linesman is there, he should assist with the decision. Everyone probably thinks it's a penalty. Do you think it's a penalty?"

Sierra failed to respond to Koeman's question, prompting the Barca boss to cut short the interview.

With this defeat, Koeman is the first Barcelona coach to lose his first two LaLiga games against Madrid since Joaquim Rife in 1980 (also the first two).

Ronald Koeman has no intention of resting Lionel Messi and Frenkie de Jong ahead of next week's El Clasico, despite both players being one booking away from a suspension.

Barca will be looking to extend their 18-match unbeaten run in LaLiga when they welcome Real Valladolid to Camp Nou on Monday.

Messi and De Jong are both available for the game as the Catalan giants look to keep the pressure on leaders Atletico Madrid, who are four points better off ahead of Sunday's trip to Sevilla.

However, both players risk being banned for next Saturday's showdown with bitter rivals Real Madrid, having each been booked four times already this season.

But while the pair may be walking a disciplinary tightrope, Koeman is ready to risk star man Messi and central midfielder De Jong against Valladolid.

"We know that these two players are one card away, but it is not the time to rest players due to cards or freshness," he said at Sunday's pre-match news conference.

"We have ten games left. There is always the risk, but the best thing is to put the team out that I think can win the game."

Messi has been directly involved in 23 league goals in 2021 - 16 goals and seven assists - which is more than any other player in the top five European leagues. 

The Argentinian has had a direct hand in eight goals in his last four LaLiga games against Real Valladolid - four goals and four assists.

Those goal involvements have helped Barca to 13 wins in their previous 14 LaLiga games against Valladolid, with the only exception being a 1-0 defeat away from home in March 2014.

Sergio Gonzalez's side have won just one of their past 11 league games, but Koeman will not take Monday's opponents lightly.

"You have to be prepared, you can't think that it will be an easy game," he said. "We have to go in with a lot of energy and rhythm and be good with the ball.

"We have to get back to our level. It could be a game without problems, but you always have to work hard to win."

Gerard Pique returned to training this week after recovering from a knee problem, while Sergi Roberto is also closing in on a comeback after two months on the sidelines.

Koeman will make a late decision on whether the defensive duo are ready to play a part against Valladolid.

"They are training with the team lately. They have improved a lot," he said.

"These are decisions that will be made tomorrow after the last training session. We aren't going to take risks [with injuries], nor next week, because there are more games coming this season."
