Arsenal must come from behind to reach the Champions League final after Ousmane Dembele’s early strike gave victory at Emirates Stadium.
Dembele stunned Arsenal when he swept home a low finish from Khvicha Kvaratskhelia’s delivery only four minutes into the semi-final first leg.
PSG dominated the early stages with a relentless attacking assault, which saw Arsenal keeper David Raya make a superb save from teenager Desire Doue.
The hosts survived without further damage to work their way into contention, and once again giant Italian keeper Gianluigi Donnarumma, as he was against Liverpool and Aston Villa earlier in the competition, was PSG’s hero.
He saved brilliantly from Gabriel Martinelli and Leandro Trossard either side of the break, while Arsenal saw Mikel Merino’s header from a Declan Rice free-kick ruled out for offside.
PSG had chances to extend their advantage late on, but substitute Bradley Barcola shot wide and Goncalo Ramos hit the bar.
