Paris Saint-Germain took a big step to the Champions League final as Ousmane Dembele's early goal beat Arsenal 1-0 in the tense first leg of the semi-finals.
Dembele fired a shot at the post office in the fourth minute as PSG dominated the opening phase in Tuesday's opening phase, with Luis Enrique's side holding the company, bringing valuable advantages back to the French capital.
Arsenal has been in the semifinals for the first time since 2009, improving after a breakthrough start and out of Mikel Merino's goal after a break, while PSG Guardian Gianluigi Donnarumma made several good savings.
PSG has survived the storm and should provide a bigger cushion for its second round, but both Bradley Barcola and Goncalo Ramos have wasted the chance of gilding.
If PSG protects their advantage at home next Wednesday, they will face Inter Milan or Barcelona in Munich, and they will believe that the first champion of the European Blue Ribs match will finally be reached now.
In the early stages of October, Arsenal comfortably beat PSG 2-0 in North London, but the French champion of Louis Enrique has evolved into a powerful force.
PSG has been a scourge for British clubs since Arsenal’s defeat, beating Manchester City in the league stage, defeating Premier League champion Liverpool in the last 16 strokes and sending Aston Villa in the quarter-final thriller.
With fanatical support, PSG roared, barely giving the pulling Arsenal a start for 25 minutes, with too many paces and movements for Mikel Arteta's side.
When the PSG hit, the smoke from the pre-match fireworks was barely cleared.
Khvicha Kvaratskhelia catches the ball on the left and pours into the area, then dials a pass to Dembele to clear David Raya's outpost.
It was Dembele's eighth and 11th goal in the season, matching the club record of former Talisman Kylian Mbappe in PSG.
Arsenal is swinging and it may get worse. Leandro Trossard was booked for eliminating Achraf Hakimi as he broke the clear game, with Marquinhos leading the way in the Hakimi Cross in Raya.
In the first half, Kvaratskhelia stabbed the side of Arsenal and screamed for punishment as he fell to the ground under suspicious challenge from Jurrien Timber.
Raya saves further from Kvaratskhelia and craves Doue, then Arsenal finally starts to clear their heads.
Gabriel Martinelli approached Bukayo Saka's cross in pain and was rejected by Donnarumma's low post at halftime.
Arsenal believed that when Merino sailed into the free kick of Declan Rice's swing, they had reached a balance directly after the break, but the long var check ruled that he was just offside.
Arteta's side was briefly in control, Donnarumma made a surprisingly low savings with PSG's defense squeaking, shooting Trossard with her fingertips.
Although Barcola has put in the effort before Ramos puts his bars, PSG may regret not leaving more.
