Bernd Leno revealed Jesse Lingard's goal celebration in Arsenal's recent FA Cup defeat to Manchester United acted as motivation as the Gunners secured victory in Sunday's Premier League clash between the top-four rivals.
Solskjaer was furious that Moss ruled Fred's challenge on Alexandre Lacazette was worthy of a spot-kick in the 69th minute.
In a keenly-fought 200th league edition of one of English football's great fixtures, Arsenal went ahead in the 13th minute when Xhaka belted a shot from 30 metres out, with United keeper David de Gea seemingly wrong-footed by the curve of the ball. "The ball moves so odd and it looks like it goes to David's left and it changed direction", he said.
Solskjaer was unhappy with the penalty decision but said his players ultimately let themselves down with a sluggish first few minutes, only four days on from their dramatic win at Paris Saint-Germain in the Champions League. "Laca gave me the penalty and that was cool from him, I was really focused", Aubameyang said on Sky Sports.
"It has been fantastic so far but today is the the lowest we have been because we lost and missed the chance to put pressure on Spurs".
Emery is looking to win the Europa League for a fourth time as a manager
Making it even sweeter, Arsenal climbed above Manchester United into fourth place in the race to qualify for next season's Champions League.
And Arsenal manager Emery has admitted that he was delighted by the German goalkeeper's performance at The Emirates.
"Our goalkeeper is very important and sometimes the goalkeeper can save us and today I'm very proud of his work", he added.
It was United's first league defeat since December 16, Jose Mourinho's last game in charge, and ended Solskjaer's remarkable three-month, 12-match unbeaten league start as his interim replacement. "The manager gave me the time and when I got the chance, I played good, so he said, "you will stay in goal".
The Gunners are two points ahead of United and only one point behind third placed Tottenham, with sixth placed Chelsea three points adrift of the top four with a game in hand.More news: UFC star McGregor arrested in Miami Beach
