Barcelona saw their 11-year run of victories in the Joan Gamper Trophy come crashing to a halt on Monday as Monaco trounced Hansi Flick's side 3-0 at Montjuic.

Flick was without several big names from the start as the Estadi Olimpic Lluis Companys played host to Barca's traditional curtain-raiser, though Robert Lewandowski started and the likes of Lamine Yamal, Ilkay Gundogan and Ferran Torres featured as substitutes.

Any hopes of a positive start to his reign were dashed by an impressive Monaco side after a goalless first half, Lamine Camara pouncing on a loose pass from Inigo Martinez to slot home a 50th-minute opener.

Breel Embolo added a second just seven minutes later, the Switzerland international timing his run to perfection before lifting a clipped finish past Marc-Andre ter Stegen.

Adi Hutter's visitors then added further gloss at the death, following a spate of Blaugrana changes. Substitute Christian Mawissa latched onto a loose ball on the right side of the area, then curled a delicate finish into the bottom-left corner to cap a poor night for Barca.

Data Debrief: Barca's long reign ends

Not since a 2012 defeat to Sampdoria had Barcelona been beaten in the Joan Gamper Trophy, with an 8-0 rout of Santos and victories over Juventus, Arsenal and Tottenham among their standout results through an 11-year winning streak.

Barca may have been without several big names, but Flick now has food for thought ahead of his first game in charge in LaLiga, at Valencia on Saturday. 

This is the first time they have lost by three or more goals without scoring in the Joan Gamper Trophy since 1981, when they were beaten 4-0 by Koln.

Pedri described playing with Robert Lewandowski as a "luxury" after both players starred in Barcelona's 6-0 demolition of Pumas UNAM in the Joan Gamper trophy on Sunday.

The Blaugrana ran riot in their traditional Camp Nou curtain-raiser, with goals from Pedri (two), Lewandowski, Ousmane Dembele, Pierre-Emerick Aubameyang and Frenkie de Jong condemning the Mexican side to a crushing loss.

Barca took just 20 minutes to establish a 4-0 lead as Pedri scored twice after laying on new signing Lewandowski's opener, with the Poland striker returning the favour to tee up the skilful midfielder's second strike.

Lewandowski – who scored 50 goals in all competitions during his final season with Bundesliga champions Bayern Munich last term – was named as man of the match, leading Pedri to shower him with praise. 

"It was important for us to win in front of our fans and we have achieved it by playing a good game," the midfielder said.

"The coach asks us all to reach the top and that we score goals, and I hope it continues like this. We've had a good pre-season and we wanted to start scoring soon.

"It is a luxury to play with Lewandowski, I really enjoy seeing how he finishes and how he links up.

"The president [Joan Laporta] and everyone have done a great job, and we will fight until May for it to be a very beautiful year for us all."

With Lewandowski joining Franck Kessie, Andreas Christensen, Jules Kounde and Raphinha in moving to Camp Nou ahead of the 2022-23 season, hopes are high that Barca can challenge for silverware – even if speculation persists that they may be unable to register their newcomers.

For Xavi, the performance against Pumas – for whom Barca legend Dani Alves featured – represented the standard the Catalan giants must hit in every match.

"Everything went well tonight, I'm very happy with the good game and for the fans, who have been excited. This is the way," Xavi declared.

"We are in a good dynamic of play and results, but we have to continue working for this to work. The sensations are good, yes, but there is no need to lower the pace or the intensity during the 90 minutes.

"Today it is understood that we relaxed a bit because we were 4-0 very early and it was a friendly, but in official competition you cannot lower your guard."

Barca begin their LaLiga campaign at home to Rayo Vallecano next Saturday.

Dani Alves is grateful that he will have the opportunity to say a final farewell to Barcelona fans at Camp Nou in one of his first games as a Pumas UNAM player.

The veteran full-back left Barcelona at the end of last season following the expiration of a short-term deal signed when returning to the club for a second spell in January.

Brazil international Alves started 14 LaLiga games for Xavi's side in the second half of last season, but the club decided against extending his contract for another year.

He will now continue his prestigious career in Mexico with Pumas, who confirmed the 39-year-old's arrival on Saturday after days of teasing the high-profile signing.

And in a coincidental twist, Alves is now expected to be part of the Pumas squad that takes on Barca for the Joan Gamper Trophy on August 7.

Barca were originally scheduled to face Roma, but Jose Mourinho's side pulled out and Pumas took up the invitation to play in the pre-season friendly.

The defender previously suggested he was unhappy with the manner of his Camp Nou exit, but he has now said he can understand Barcelona's decision.

"In the end, life treats people who treat life well, and this game gives me the right to come and play with Pumas at Camp Nou to say goodbye," he told TUDN News. 

"My contract there ended. I didn't expect much more as I'd only signed for six months and fulfilled those.

"But now, I will have the opportunity with Pumas to say goodbye to the people as I would have always liked."

Alves scored one goal and set up four more between his second debut on January 5 and the end of the 2021-22 campaign.

That is a tally bettered only by Ferran Torres (six), Jordi Alba (seven) and Ousmane Dembele (11) among Barca players over that period.

Despite recently turning 39, Alves made clear he wanted to quickly find a new club in order to remain part of Tite's plans for the 2022 World Cup.

Asked why he opted for Mexico, and Pumas in particular, Alves said: "What attracted me to this club is more than just football.

"I think that in Mexico, you have to try to believe a little more in their football. 

"Those who out of ignorance discredit Liga MX, do it wrongly. There are very good goalkeepers, who we have faced at the Olympics. 

"When we went to the Club World Cup with Barca, the Mexicans were the only ones who wanted to face us."

Barcelona are studying the possibility of taking legal action against Roma after the Italian club announced they will no longer take part in the Joan Gamper Trophy. 

The two clubs were set to meet at Camp Nou on August 6, with their respective women's sides also facing off, in a fixture that acts as an annual curtain-raiser for Barca's season.

However, just 12 days after the friendly was announced, Roma confirmed on Monday that they have withdrawn from the match.

Roma said in a statement the decision was taken as a result of modifying their pre-season plans to best suit both their men's and women's sides.

In a strong statement of their own released shortly thereafter, Barcelona hit out at the Europa Conference League winners, who are managed by their former coach Jose Mourinho.

"Roma have decided to unilaterally, without reason, withdraw from the agreed contract for both parties for the Joan Gamper Trophy," the statement read.

"The club is working on a finding a new opponent for this year's edition. In the next 24 hours the return of money already spent on tickets will begin.

"The club wants to make it clear that the suspension of the games has been due to circumstances outside the control of FC Barcelona, the express wish of AS Roma. 

"The club's legal department is studying possible action against the Italian club for damages caused to Barcelona and its fans due to this unexpected and unjustified decision."

Barcelona are scheduled to face UE Olot, Inter Miami, Real Madrid, Juventus, New York Red Bulls and Manchester City ahead of the start of the 2022-23 LaLiga season.

Jose Mourinho will return to Camp Nou in August to face Barcelona with his Roma side in the Joan Gamper Trophy.

The Gamper acts as the curtain-raiser for Barcelona's season, with the Blaugrana taking on Juventus in last year's edition, which was the first to involve both the men's and women's teams.

Barcelona announced on Wednesday that Roma are the chosen opposition for this year's version, with the games set to take place on August 6.

Mourinho will head back to the Camp Nou, where he was Louis van Gaal's assistant for three seasons until 2000, on the back of lifting the Europa Conference League with Roma.

The Portuguese coach is a largely unpopular figure among Blaugrana supporters after managing fierce rivals Real Madrid.

Mourinho guided Madrid to a LaLiga title, Copa del Rey crown and the Supercopa de Espana in his three seasons with Los Blancos.

It will not be the first appearance for Roma in the Gamper either, after the Serie A side were beaten 3-0 by Barcelona in the 2015 edition.

Gerard Pique has put Lionel Messi's imminent departure from Barcelona down to the former board's poor running of the club.

The Catalan giants announced in a shock statement on Thursday that Messi will not be extending his 21-year stay at Camp Nou due to the club's dire financial situation.

Messi, who scored 672 times in 778 appearances for the LaLiga side, is now expected to complete a free transfer to Paris Saint-Germain.

Despite the Argentina international agreeing to take a 50 per cent pay cut, Barcelona were unable to honour the new contract agreed with him due to LaLiga's salary cap limit.

Barca are estimated to be in around €1.2billion of debt, a hangover from the previous Josep Maria Bartomeu regime which spanned from 2014 until 2020 when he was ousted.

Pique has spent the last 13 years playing alongside Messi and believes the situation could have been avoided.

"This has not been one of the best days for us. We have lost the best of all time," Pique said following Barca's 3-0 win over Juventus in Sunday's Joan Gamper Trophy clash at Estadi Johan Cruyff.

"We knew this day would arrive, but the team was still touched, especially those of us who spent many years sharing a dressing room with him.

"The management of recent years has not been the best and that has penalised us."

Messi's name was chanted throughout the prestigious friendly with Juve, with goals from Memphis Depay, Martin Braithwaite and Riqui Puig earning Barca a routine victory.

Ronald Koeman spoke ahead of the game about an exciting future despite the loss of Messi and reiterated after the victory that it is important his side put the saga behind them.

"It is normal that when a player like Messi leaves it will be hard for everyone, but we have to turn the page because we cannot change this situation," he said.

"You have to play well and win, work more. Others can occupy that position and have a leading role. But we will no longer have Leo. We have to turn the page and be hopeful."

Messi's departure could have a knock-on impact for Koeman, with fellow Argentina international Sergio Aguero reportedly looking to leave Camp Nou before kicking a ball.

Aguero was ruled out of Barca's final pre-season outing with a calf problem, but Koeman denied suggestions the striker wants to terminate the contract signed just last month.

"That is not true," Koeman said. "He has signed and is excited. It is a pity that he was injured this morning. 

"We have to wait for his recovery. It happened in training. We know that when he is fit he can contribute a lot."

Among a number of positives on the field for Koeman during pre-season has been the form of new signing Depay, who took just three minutes to open the scoring against Juve.

The Netherlands international has three goals in four matches since arriving on a free transfer from Lyon, emphasising Koeman's point of there being life after Messi.

"Memphis showed again today that he can be very effective," Koeman said. "We know we must score more and the squad must improve.

"The best in the world will be missed, but you have to accept it. We are not living in the past. There is a future for this team.

"This result against Juventus was very good and achieved by playing some good football. We have taken another step and will only get better when other players return."

Barcelona kicked off the post-Lionel Messi era with a 3-0 win over Juventus in Sunday's Joan Gamper Trophy clash at Estadi Johan Cruyff.

Messi gave a tearful farewell to Barca at a news conference on Sunday after it was confirmed this week the forward's 21-year association with the club has come to an end.

The six-time Ballon d'Or winner's name was chanted by home supporters throughout the prestige pre-season match with Juve, who included Cristiano Ronaldo in their starting line-up.

Memphis Depay gave Barca the lead after three minutes and Martin Braithwaite added a second before the hour mark as Ronald Koeman's men rounded off pre-season with a win, with Riqui Puig scoring a fine third with the last kick of the contest.

New signings Yusuf Demir and Depay linked up for Barca's early opener, with the latter taking a throughball in his stride and picking his spot past Wojciech Szczesny.

That was Depay's third goal in four games since arriving from Lyon on a free transfer and he nearly had a second soon after when bending a free-kick narrowly over the crossbar.

Ronaldo was kept largely quiet during his 45 minutes on the pitch but did test Neto with a vicious shot in the first half, while Alvaro Morata was twice denied by the Barca keeper.

The hosts had some breathing space 12 minutes into the second period as Braithwaite's header from a Depay corner squirmed through the grasp of substitute keeper Mattia Perin.

Barca added a third goal to their tally in the final seconds through young midfielder Puig's curled effort from 20 yards to give Koeman hope of a bright future without club legend Messi.

Philippe Coutinho is set to make his long-awaited return from injury in Barcelona's Joan Gamper Trophy showdown with Juventus on Sunday.

The Brazilian has been passed fit and could play his first football for Barca of 2021, having undergone two knee surgeries since the turn of the year.

The attacking midfielder last played for the Catalan giants in their 1-1 draw with Eibar at the Camp Nou in December.

Ronald Koeman has also named the likes of Memphis Depay, Antoine Griezmann and Martin Braithwaite in his 21-man party for the club's annual season curtain raiser at Estadi Johan Cruyff.

However, Sergio Aguero and Clement Lenglet are missing for Barca, who begin their LaLiga campaign at home to Real Sociedad on August 15.

Aguero, who arrived from Manchester City on a free transfer, is set to undergo further tests on a right calf injury, while defender Lenglet has a tendon problem in his right knee.

Barca are seeking their ninth successive victory in the Joan Gamper Trophy, which they have won 43 times since the inaugural event in 1966.

Juventus, who launch their Serie A season away at Udinese on August 22, are one of the 11 teams to have denied the Blaugrana.

The Bianconeri prevailed on penalties in the 2005 showpiece.
