Alexis Sanchez is one of those footballers that can produce something out of nothing.
He is easily inside the top 20 best players in the world, and Arsenal are lucky to have his services.
However, things could have been very different.
After one of the most long-running transfer sagas this summer, Arsenal fans breathed a huge sigh of relief as when the transfer window closed Sanchez was still a Gunner.
Manchester City thought they had a deal wrapped up in the closing stages of the window, but Arsenal remained firm.
With the Chilean's contract set to run out in 2018, Wenger refused bids in excess of £40 million, instead choosing to run the risk of letting Sanchez move on for free next summer.
But after today's piece of magic against Brighton, you can understand why the Frenchman was so desperate to keep the 28-year-old.
After some neat build up play, Aaron Ramsay fed the ball into Sanchez's feet inside the box.
With men surrounding him from all angles, the former Barcelona man played an incredible back-heel right into the path of Alex Iwobi, who made no mistake from ten yards.
It was a brilliant piece of play from Sanchez and you can view the goal here:
Iwobi's goal came after Nacho Monreal had opened the scoring for the home side on the 16th minute.
Arsenal would eventually emerge victorious by a 2-0 scoreline, which lifted them into 5th position.
After a poor start to the season, Arsene Wenger's men have managed to transform their fortunes with six wins from their past seven outings in all competitions.
Their only blemish in this run came in the shape of a 0-0 draw away at Chelsea, meaning Arsenal's last seven results have all been positive.
Wenger will also be happy that his side have managed to keep five clean sheets during this run; especially after he watched his team ship eight goals in their opening three Premier League fixtures.
Despite their surge up the table in recent weeks, Arsenal are still six points behind joint leaders Manchester City and Manchester United, but recent form suggests they could close the game even further in the coming months.
