Arsenal maintained their perfect start to the Europa League as Bukayo Saka's goal clinched a 1-0 win at Bodo/Glimt, while Manchester United left it late to beat Omonia Nicosia.
Saka struck midway through the first half in Norway to give the Gunners a third win in as many outings in Group A.
"I'm really happy with the win against a team that has won the last 14 games here at home," Arsenal coach Mikel Arteta told BT Sport.
"We were expecting a really tough night here and we made a lot of changes again but I'm delighted to find a way to win."

Scott McTominay spared United's blushes with a 93rd-minute goal in a 1-0 win over Cypriots Omonia at Old Trafford.
Omonia goalkeeper Francis Uzoho pulled off a string of fine saves to frustrate a wasteful United before the Scotland midfielder fired home in stoppage time.
"You have to be patient sometimes. Their goalkeeper was a different class but we created enough chances and deserved to score in the end," McTominay told BT Sport.
"It's a massive goal because we need to win the group."
