Mikel Arteta saluted "unbelievable" Kai Havertz after the German inspired Arsenal's 2-0 success against Paris Saint-Germain as the Gunners secured their first win in the Champions League this season.

Havertz headed Arsenal into the lead and Bukayo Saka netted before the interval to underline their superiority at the Emirates Stadium.

After drawing their opening league phase tie at Atalanta, Arteta's side moved onto four points in their bid to reach the knockout stage of the revamped tournament.

Eliminated by Bayern Munich in the Champions League quarter-finals last season and pipped to the English title by Manchester City, the Gunners are now unbeaten in nine games in all competitions this term as they chase silverware on both fronts.

"The first half was very dominant, how determined and brave we were," Arteta said.

"We suffered more than we should have in the second half. The Champions League brings different demands but we handled it well.

"I'm really pleased. It's good for our belief. We put our stamp on how we want to play against the best teams in Europe."

Praising Havertz's influential display, Arteta said: "He has been unbelievable. His football brain and work ethic are incredible.

"Now he is a real threat around the box. He is one of our main players at the moment."

There was further good news for Arsenal as Spain midfielder Mikel Merino made his long-awaited debut for the last 30 minutes.

Merino's recovery from a shoulder injury suffered in his first training session following his close-season move from Real Sociedad was a welcome boost for Arteta with Martin Odegaard currently sidelined.

PSG boss Luis Enrique slammed his players, saying: "Arsenal were much better than us, in terms of intensity and in the duels.

"It's impossible to come out of the game with a positive result if you don't win any of the duels. From the first minute Arsenal were superior to us. They deserved to win."

Havertz rewarded Arsenal's relentless pressure with the opener in the 20th minute.

Leandro Trossard curled a pin-point cross into the six-yard box and Havertz made a perfectly-timed run behind the visitors' flat-footed defence to bravely head past advancing keeper Gianluigi Donnarumma.

Havertz, who scored Chelsea's Champions League final winner in 2021, endured a difficult start with Arsenal after moving across London for £65 million ($86 million) last year.

But since the start of February, only three Premier League players have more combined goals and assists in all competitions than Havertz's tally of 21 as he banishes the 'waste of money' jibes.
