Arsenal have it all to do if they want to reach the Champions League final after Ousmane Dembele's early goal handed PSG a 1-0 victory at the Emirates Stadium, Sky Sports reported.

PSG made a blistering start through Dembele before world-class saves from Gianluigi Donnarumma to deny Gabriel Martinelli and Leandro Trossard kept the Gunners at bay.

It was a frustrating night for Arsenal, who saw Mikel Merino's header ruled out for offside, with the fans venting their fury at referee Slavko Vincic at half-time and full-time, but it could have been even worse for the north London side had PSG taken one of two clear-cut chances in the closing stages.

Mikel Arteta's side now face an uphill task in next week's second leg in Paris as they look to keep alive their dream of a first Champions League success in the club's history.

Arsenal travel to France for the return leg against PSG next Wednesday at the Parc des Princes.

But before that, the Gunners host Bournemouth in the Premier League's late afternoon kick-off on Saturday, live on Sky Sports, while PSG head to Strasbourg in Ligue 1 earlier on the same day.

The Champions League final takes place on Saturday May 31 at the Allianz Arena in Munich, with the winner of this semi-final tie taking on either Barcelona or Inter Milan.
