The Chile international has been one of the Gunners’ most consistent performers since his arrival at the club from Barcelona in the summer of 2014.
The 27-year-old has developed into a talismanic figure at Emirates Stadium, and has scored 10 goals in all competitions for the Gunners so far this season.
And the former Udinese and Barcelona star insists that he remains fully committed to the north London side.
Sanchez told Arsenal’s website ahead of their 3-2 loss to Manchester United on Sunday: “Arsenal are very supportive and we are happy at the club.
“Arsenal is now my family. It’s very fun [to be here] and now the focus is on the Premier League.”
He continued: “It’s about the [important] moments. For example Leicester was a difficult game but the support was very strong for the team.
“For the players, it was really important to win against Leicester.”
Sanchez and his Arsenal team-mates will be looking to bounce back from their disappointing defeat at Old Trafford when they host Swansea City in the Premier League at The Emirates on Wednesday night.
The Gunners head into the game in third place in the table and three points behind leaders Leicester City.
