Arsenal's 2-0 win over Manchester United on New Year's Day was a welcome relief for all connected to the club.
For Mikel Arteta it was his first win since being appointed head coach and for the supporters it was the first time since early October that they had seen their team taste victory at the Emirates Stadium in a Premier League game.
First-half goals from Nicolas Pepe and Sokratis were enough to get the job done against the Red Devils to send the Gunners into the top half of the table.
Overall it was an impressive showing from the Arsenal players with Pepe, Mesut Ozil and Lucas Torreira among those to earn big praise from the media and fans alike.
Just as important to the victory was David Luiz.
The Brazilian has had his fair share of criticism ever since his £8m transfer from Chelsea in the summer, but has arguably been one of the standout performers under Arteta's reign thus far.
And it would appear that the 32-year-old is taking on more responsibility behind the scenes.
As spotted at around the 3.42 mark in Arsenal's 'All Access Areas' video uploaded to their YouTube account, Luiz can be seen in deep conversation with Torreira and Ainsley Maitland-Niles in the tunnel just before the teams are about to walk out on to the pitch.
Luiz continues to share information for around 20 seconds and whatever he said did have a big impact as both players were excellent in the 2-0 win.
Afterwards, Luiz gave an impassioned interview regarding what has gone wrong at the Emirates this season.
"Yeah I think it was great," he said in his post-match interview with BT Sport. "We did a great first half and we were a mature team in the second half because we have to be honest and humble to admit that physically we are not ready.
"We showed that second half against Chelsea and we showed that today. But when physically you are not there you have to put your hearts and this team is in the moment now to change a lot of things.
"We can not change zero to 10 in one day. one week, or one month. But it is beautiful to see the kids how they start to understand the commitment, the behaviours and what they have to do every single day to achieve big things in life and big things in football.
"So I think we showed that today and we are going to do big things in the future, but step-by-step."
