All in all, that will go down as an incredibly frustrating night for Arsenal.
    
    
            There were some half-hearted boos aimed at referee Slavko Vinčić when he blew for full time, but Gunners fans will know their team didn’t do nearly enough to win that game.
    
    
            It was a night that promised so much. It was the first time a Champions League semifinal had been played at the Emirates in 16 years and one of the biggest occasions in the history of Arsenal Football Club.
    
    
            Fans turned the volume up to 11 in the build-up to a game you could sense was something special to all involved in north London.
    
    
            But Ousmane Dembélé’s early goal was the perfect antidote for Paris Saint-Germain to counteract a hostile crowd inside the Emirates.
    
    
            PSG impressively managed the game from then on, breaking up play with fouls or extended treatment for players who went down injured to ensure Arsenal could never find any real rhythm.
    
    
            Across the pitch, players were relentless in their pressing and hounding of the opposition. Vitinha and João Neves in particular barely allowed the Arsenal midfielders space to breathe.
    
    
            The Gunners are formidable opponents at home and were unbeaten in 11 Champions League games at the Emirates coming into this evening, including nine clean sheets.
    
    
            Just scoring a goal here in north London is difficult enough, much less winning a match. PSG did both after winning the first leg 1-0.
    
    
            Afterwards, Paris Saint-Germain manager Luis Enrique was keen to highlight just how far this tie is from being over. As it did on Tuesday in London, an early goal in the second leg in France could quickly alter the course of the tie.
    
    
            “I think the match had different phases,” Enrique told reporters. “At the start, there was an incredible atmosphere and impressive noise. It was deafening but we scored an early goal and that gave us a lot of confidence.
    
    
            “Arsenal began to dominate more in the second half and were dangerous. The result is good. It could have been better, and it could have been worse,” he said.
    
    
            “Everything can change with one goal. We lost the first leg against Liverpool at home and then went to Anfield and won.”
    
    
            There will be thousands of delighted Parisians heading back on the ferry or Eurostar over the next couple of days and after that performance, they will rightly be feeling confident of finishing the job.
    
    
            Arsenal, meanwhile, has plenty of work to do ahead of the return leg.
    
    
            Mikel Arteta’s team struggled to break down PSG’s defense and will need to find some solutions.
    
    
            Despite a disappointing and frustrating evening, Arteta was cool, calm and collected in his post-match press conference.
    
    
            The Arsenal boss frequently reiterated that he believed the margins between victory and defeat were small, and said he maintains full belief in his team turning it around.
    
    
            Just as he didn’t get carried away after hammering Real Madrid 3-0, Arteta wasn’t despondent after the defeat.
    
    
            “My message will be exactly the same as it was after Real Madrid 3-0 at home,” Arteta said. “We have to go to Paris and win the game, which we are capable of. I saw two great teams today and the margins are so small.
    
    
            “This team (PSG) has beaten all of the English teams in the Champions League, you cannot dominate this team for 95 minutes,” he said.
    
    
            “If you want to be in the Champions league final you have to do something special, and we’ll have to do something special in Paris to get there.”
    
    
            The two sides will battle again in the return leg set for the Parc des Princes on May 7 with a place in the Champions League final at stake.
