Substitute Ferran Torres snatched the only goal of the game as Barcelona extended their 100 per cent start in Champions League Group H with a hard-fought 1-0 win in Porto.
The hosts had most of the chances but were undone by a blunder from Romario Baro in first-half injury time which allowed Torres to go through and slide the ball past Diogo Costa.
It was not all plain sailing for the visitors, who had to survive a torrid late spell which culminated in Gavi being sent off in injury time for a second yellow card.
On a history-making night for Barca, Xavi named Lamine Yamal in his line-up, making him the youngest starter in Champions League history at 16 years and 83 days old, beating the previous record held by Celestine Babayaro.
The teenager provided plenty of threat in the visitors’ front line, as did former Benfica star Joao Felix, who was given a tasty reception on his return to Portugal.
Baro should have done better with a Joao Mario cross in the seventh minute but failed to get his shot off in the box, then Pepe’s touch also let him down after being fed by the dangerous Mehdi Taremi.
Barca keeper Marc-Andre Ter Stegen comfortably gathered a tame effort from Stephen Eustaquio and it was not until the 23rd minute that the visitors fashioned a real chance when the ball fell to Felix on the edge of the box but he fired just over.
Robert Lewandowski’s night was ended by an apparent ankle injury on the half-hour mark and he was replaced by Torres, but it was still Porto who threatened with Wendell in particular posing problems down the left flank.
But Baro undid all Porto’s good work on the stroke of half-time, when his blunder allowed Ilkay Gundogan to intercept and he raced clear and fed Torres, who did the rest.
Barca came close to extending their lead early in the first half when Yamal poked a shot on the turn at Costa, then Felix almost sprang onto a Torres through-ball.
But the visitors were grateful to Jules Kounde on 54 minutes after the defender got a foot in to deny what looked like a certain equaliser after Pepe had been sent through on Ter Stegen.
As the game strayed beyond the hour mark, Taremi and Wendell had half-chances for the hosts, who also had a strong penalty claim rejected by VAR after Joao Cancelo appeared to handle in the box.
Porto continued to press and Taremi had the ball in the net in the 83rd from a sublime overhead kick but was ruled clearly offside.
In a torrid final few minutes Gavi was dismissed before Francisco Conceicao twice came close to an elusive equaliser.
Bristol City Women 0-4 Man City Women: Hosts relegated as Fowler double inspires WSL leaders
Mary Fowler scored twice to set WSL leaders Manchester City on their way to a 4-0 rout of Bristol City, who suffered relegation as a result, on Sunday.
With Arsenal having drawn with Everton earlier in the day, Man City knew a victory would be enough to take the title race down to two teams.
That victory duly arrived in emphatic fashion, with all four of Man City's goals arriving in the second half.
Fowler's fantastic strike opened the scoring in the 62nd minute, with the Australia international doubling her tally soon after, paving the way for an Amy Rodgers own goal and Alex Greenwood's late header to seal a huge victory.
Arsenal are now out of the title race, with Chelsea - who have two games in hand on Gareth Taylor's team - the only side capable of catching Man City.
The Robins, meanwhile, will be playing in the second tier again next term.
Data Debrief: Bristol heading down with a whimper
Bristol City have failed to score in their last five games in the WSL, a run of 544 minutes without a goal.
They mustered just 0.09 expected goals (xG) to Man City's 3.4, with the visitors having now kept a clean sheet in nine of their 20 league games this season.
De Rossi demands more from 'tired' Roma ahead of crunch run
Daniele De Rossi acknowledged his Roma team may be tired, but he insisted they must not allow themselves to be embarrassed.
Roma fought back to draw 2-2 with last season's Serie A champions Napoli in a pulsating fixture on Sunday.
Tammy Abraham's late header secured a point for De Rossi's team, who took the lead through Paulo Dybala's penalty before going behind to goals from Matias Olivera and Victor Osimhen.
With Serie A set to have five teams in the Champions League next season, Roma occupy fifth spot with four matches remaining, but sixth-placed Atalanta are just two points behind with a game in hand.
There is also the small matter of a Europa League semi-final against Bundesliga champions Bayer Leverkusen on the cards over the coming weeks, and De Rossi set the stall out.
"We drew, it is not a result to throw away, but it is not the result or the performance that we wanted," Roma coach Daniele De Rossi told Sky Sports Italia.
"At times you can steal the ball off Napoli, but we then gave it back again too many times. Napoli had a lot of chances in the first half, we did better in the second, but we have to do better.
"Look, we are tired, but we cannot start thinking that we’re tired and that means we can be embarrassed in the final few weeks of the season."
Roma host Leverkusen on Thursday before taking on Juventus on May 5, with a crunch clash against Atalanta – who are also into the Europa League semi-finals – set to follow after the away leg against Xabi Alonso's team.
Key to a successful end to the campaign for Roma will be keeping Dybala fit. The Argentine has been involved in the joint-most goals (12) in Serie A since the turn of the year, scoring nine and setting up three, level with Juve's Dusan Vlahovic.
PSG's latest Ligue 1 title arrives as Monaco lose to Lyon
Paris Saint-Germain have been crowned as Ligue 1 champions after Lyon overcame Monaco 3-2 on Sunday.
A 4-1 midweek win over Lorient ensured that one more victory would be enough for Luis Enrique's team to get over the line, but PSG failed to get the job done themselves when they faced relegation-threatened Le Havre on Saturday.
That game was the 700th match of the QSI era at PSG, and the club's 1,900th in France's top flight.
However, PSG's wait to win their third straight title did not last long, as less than 24 hours later, Lyon – who will face the Parisians in the final of the Coupe de France at the end of May – came out on top in a topsy turvy encounter with second-placed Monaco.
Substitute Malick Fofana was the matchwinner for Lyon, and ultimately the player who handed the title to PSG.
Wissam Ben Yedder had put Monaco ahead in the opening minute, but quickfire goals from Alexandre Lacazette and Said Benrahma turned the match on its head before half-time.
Ben Yedder netted his second to restore parity on the hour mark, and thought he had sealed his hat-trick when he volleyed in from a free-kick, only to have strayed offside.
With only a win good enough for Monaco to stay in the fight, the visitors were then caught out in the 84th minute, with Fofana racing onto Lacazette's throughball and finishing calmly.
After a dismal start to the season, relegation looked a real possibility for Lyon, but they are now, with three games remaining, still in with a shout of qualifying for Europe.
PSG on the other hand now have 12 Ligue 1 titles to their name, with 10 of those coming under QSI's ownership. Aside from the COVID-impacted 2019-20 season, five of their last six league titles have been secured before the start of May.
It also means Luis Enrique remains in the running for a treble in his first season at the club, with PSG taking on Borussia Dortmund in the Champions League semi-finals next week.
