Mikel Arteta earned his first win as Arsenal head coach as the Gunners beat Manchester United 2-0 on New Year's Day.
First half goals from Nicolas Pepe and Sokratis were enough to seal an important three points against Ole Gunnar Solskjaer's side, who struggled against Arsenal's energy and high pressing for long periods of the game.
Speaking after the game, Arteta paid tribute to supporters: "I said to the players, ‘it is up to you, your body language and behaviour, if you are able to transmit to them, they will buy into it.
"If it is negative, it is a negative [reaction from the fans], if it is positive, it is positive and they are willing to help you guys. They are here to support you'.
"They are fans and they want to see their team perform like they did today.
"Thank you so much to them because when they are right behind [the team], you can tell the confidence and the things they tried, and the energy had towards the game you could see it was much better."
As well as tasting victory for the first time in his career as a head coach, the result against United was significant for Arteta because of one reason in particular.
Arsenal's win was the first time Manchester United have lost against a traditional 'big six' side this season.
Solskjaer's side are the only team in the Premier League to take points off leaders Liverpool in the 1-1 draw at Old Trafford, whilst they have also earned league wins over Manchester City, Tottenham Hotspur and Chelsea.
United beat Jose Mourinho's Spurs 2-1 at Old Trafford in December, before following it up with an even more impressive 2-1 win in the Manchester derby at the Etihad a few days later.
Chelsea were also beaten 4-0 at Old Trafford on the opening weekend of the season.
After the match, Red Devils boss Solskjaer admitted Arsenal deserved the victory, with the Gunners' second goal a key turning point in the game.
"After they scored the first goal it seemed like they had loads of energy," the Norwegian said.
"Their heads got loads of energy and ours were a little bit tired. They were the better team, aggressive, regained the ball we couldn't find a way out of their press.
"It was hard to get the ball off them because I thought they played really well."
