Kai Havertz and Bukayo Saka inspired Arsenal's 2-0 success against Paris Saint-Germain on Tuesday as the Gunners secured their first win in the Champions League this season. Havertz headed Arsenal into the lead and Saka netted before the interval to underline their superiority at the Emirates Stadium. After drawing their opening league phase tie at Atalanta, Mikel 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. 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.
