The 26-year-old has been on international duty with Chile in recent days but is now heading back to the UK as the Gunners ramp up their preparations for Saturday’s clash with Watford.
Sanchez posted the picture above on his personal Instagram account and wrote: “Now fully focused on the arsenal … Let’s Go GUNNERS ”
Sanchez scored twice and was named man of the match as Arsenal sealed an impressive 3-0 win over Manchester United in their most recent top-flight outing.
That win left Arsene Wenger’s men second in the Premier League table and two points behind leaders Manchester City.
Sanchez, who joined from Barcelona last summer, has been in fine form for the north London club in recent weeks and has already scored five Premier League goals for the Gunners this term.
