We’d imagine most Arsenal fans are still reeling over their side’s emphatic 4-2 victory of Spurs on Sunday - and rightly so.At 2-1 down, the Gunners had their backs against the wall. But, a brace from Pierre Emerick-Aubameyang helped spur the side to chase after all three points.The side’s performance held a demeanour and spirit that we haven’t seen from Arsenal for quite some time. One moment from the game, in particular, displayed this perfectly.Sokratis Papastathopoulos is one of the many new additions Unai Emery brought in during the summer to help kickstart a new era at the club.It’s taken some time for the former Borussia Dortmund man to adjust to life in the English top flight. However, it seems as though an incident involving him during the derby has won the hearts of Arsenal fans across the country.One Twitter user posted a video drawing attention to Sokratis’ reaction after winning a vital challenge against Christian Eriksen in the 83rd minute.He wrote: “Look at Sokratis...Celebrating a tackle. We have not had this type of winning mentality in years. I love it.”Sokratis can be seen visibly ecstatic with the challenge, and it’s easy to see why. Had he not been successful, Eriksen would have been through on goal. And with a player of Eriksen's calibre, that's a risk not worth taking.

It appears the incident has sent fans into a frenzy. To be fair, they haven’t seen a player show that much passion for quite a while.

One fan responded: "On the 83rd minute and up 2 goals! What a derby still buzzing."

Meanwhile, another wrote: "He does it every time he makes a winning tackle. I noticed it against Bournemouth already. Absolutely love that attitude."

Emery seems to have instilled a new-found belief into his players, and that belief has translated into success on the pitch.

It's been a tepid spell for the Gunners during the latter stages of Arsene Wenger's tenure. However, from what we've seen already this season, things are looking up.
