LONDON, Oct 22 — Viktor Gyokeres scored twice to end a nine-game goal drought in Arsenal’s second half demolition of Atletico Madrid as a 4-0 win extended the Gunners’ perfect Champions League start on Tuesday.

Gabriel Magalhaes and Gabriel Martinelli opened the floodgates before Gyokeres’ double, with all the goals coming in a 13-minute spell either side of the hour mark.

The Premier League leaders are also sitting pretty alongside last season’s finalists Paris Saint-Germain and Inter Milan at the top of the Champions League table as the only sides so far with nine points from their opening three games.

Gyokeres’ lack of goals had been one of very few concerns for Mikel Arteta in a stunning start to the campaign.

The Sweden attacker, signed from Sporting Lisbon to end Arsenal’s lack of a clinical number nine, had previously scored just three times, in home games against Leeds and Nottingham Forest, in 11 previous appearances.

“Hopefully it’s the start of some beautiful sequence now,” said Arteta.

“That’s what we brought him here for. His demands on himself are really high, but we value a lot of the things that he does for the team.”

Atletico remain without an away win all season and the manner of the Spanish side’s collapse after a competitive opening hour will concern Diego Simeone.

Another clean sheet means Arsenal have still only conceded three times 12 games in all competitions this season.

Julian Alvarez twice could have put the visitors ahead as he failed to make the most of a poor David Raya clearance in the first half and then hit the bar from outside the box early in the second period.

Eberechi Eze’s deflected effort also came off the woodwork in Arsenal’s best attempt of the first 45 minutes.
