Arsenal held on to a narrow victory in its to the Europa League opener after a couple years outside continental action.

The Gunners beat FC Zürich 2-1 thanks to goals from Marquinhos and Eddie Nketiah. The England striker set up the Brazilian for their first goal, while they essentially swapped roles for the second. Zürich managed to make things interesting when Mirland Kryeziu converted from the penalty spot.

Manager Mikel Arteta handed full debuts to the aforementioned Marquinhos, Fabio Vieira and USMNT number one Matt Turner. The Gunners dominated both possession (72%) and total shots (18), but just edged the hosts where it counts.

Fellow Premier League team Manchester United, however, failed to get off to a good start in their opening European game. United suffered a surprise 1-0 loss to Real Sociedad at Old Trafford. The only goal of the game came from a very controversial penalty in the second half.

Replays showed the Sociedad shot came off of Red Devils defender Lisandro Martinez’s arm. Yet, the ball clearly first glanced off of his knee. Nevertheless, VAR agreed with the original decision.

Sociedad picked up its first win against English opponents in the club’s history in European competition.
