Arsenal players venting their feelings on social media seems to be quite the trend at the moment.

Last week, Mesut Ozil hit back at his critics on Facebook and now Alexis Sanchez has admitted that he is growing "tired" of all the flak that he has been receiving.

The 28-year-old was speaking specifically about the criticism aimed in his direction on the international stage with Chile.

Sanchez posted the lengthy Instagram message after his nation suffered a 1-0 defeat to Bolivia, which hampers the team's chances of qualifying for next summer's World Cup in Russia.

"And tomorrow is coming. You get tired for being criticised with or without reason, you get tired of wanting to be defeated, you get tired of saying to yourself 'once more I'll get up' after crying after a defeat, and you get tired of telling the world and people who are with you, that everything is going well.

"And the worst, is that no one ever realizes how that makes you feel ... I have the 7 of Chile on my back and it is a huge responsibility, that's why it pains me that journalists and bad people criticize without knowing..."

As it stands, Chile sit sixth in the South American qualification table with two games left to play, but only the top four make it through automatically.

Sanchez's frustration comes after he failed to secure a move away from Arsenal before the close of the transfer window.

According to the Daily Mail, the forward was keen to sign for the two-time Premier League champions, but the £60m deadline-day switch fell through after Arsenal failed to sign Monaco's Thomas Lemar as a replacement.

Sanchez will be free to hold talks with suitors in January regarding a potential move as he will be a free agent at the end of the season.
