The north London side have struggled to find consistent form in the Premier League in recent weeks and slumped to a disappointing 3-1 loss to Chelsea at Stamford Bridge on Saturday.
That result left Arsene Wenger’s men in fourth place in the Premier League table and 12 points behind the leaders in the top flight.
The Gunners will look to get their season back on track when they host Hull City at The Emirates on Saturday lunchtime.
However, Sanchez enjoyed spending some time away from the training pitch with his young niece.
The Chilean shared the photo above on his personal Instagram account and wrote the caption: “I like the stars and you had the universes in your eyes. How I was not going to love you. 😊🌹❤ Chi Chi ❤ 🇬🇧”
Arsenal are looking to build on their second-placed finish in the Premier League table last season as they look to win a trophy this term under Arsene Wenger.
