The Chilean superstar has been the team’s star performer this season after managing to score 20 goals in all competitions so far.
However, the joy of watching Sanchez find his best form has been marred by rumours about his possible departure this summer.
The 28-year-old, who has reportedly attracted the interest of rival clubs, is yet to sign an extension to his contract which will expire in just over a year.
With speculation continuing to link him with a move away from Arsenal, Sanchez has been posting cryptic messages on social media concerning his mood.
And in his latest post on Instagram, the former Barcelona star wrote: “Do not compare yourself with anyone, keep your head high and remember: you are neither better nor worse, it’s just you, and no one can beat it”
