Injuries have played a part in Sanchez's off-colour performances but he insists he loves Arsenal and wants to stay. He is also relishing today's game against Manchester United, who he scored twice against in a 3-0 win earlier this season.
Sanchez said: “Tuesday in the Champions League was a difficult game. But Arsenal's support was great.
“I'm very happy here as Arsenal is now my family – it's great fun. Now the focus is on the Premier League.
“We are in a position for the title. Our home game against United was the best match we've played.
“That day, before we all went out for the match, you could see we all had this hunger to win."
