Analysis: Pleasing result for Arteta
Arsenal had to fight hard at the Estadio Metropolitano but were solid defensively - and although they lacked a consistent attacking threat, they were unlucky to leave Madrid without a win. Viktor Gyokeres had one of his better nights in an Arsenal shirt. He may look awkward at times leading the line, but his confident penalty gave the Gunners a platform in the match.
One of the forward's best attributes is his ball striking and he never looked like he was going to miss from the spot when given the chance. Manager Mikel Arteta has made a big point this season of saying how his 'finishers' - his substitutes - will make the difference in key moments. That was nearly proved right again as substitute Eberechi Eze sought to make an impact - but he was denied a penalty after going down following contact from David Hancko.
David Raya needed to make some key saves to stop Arsenal from going behind and Atletico did hit the crossbar. Arsenal will also feel that the penalty given against them was harsh, considering the ball hit Ben White's leg before striking the defender's hand. But the Gunners can take confidence from the fact that they will kick off on level terms with home advantage next week.
